American Wedding (2003) / American Reunion (2012)
How Many Years Between Sequels: Nine years.
Do They Acknowledge The Gap? Wisely ignoring the 'non-canon' DTV sequels that only Eugene Levy bothered to turn up for (well, the mortgage isn't going to pay itself), Reunion actually picks up 13 years after the events of Wedding .
Jim (Jason Biggs) is ensconced in sex-free married life when he heads home for his high-school reunion.
Cue the expected sex gags, full-frontal nudity and drunken misadventures. Some things never change.
Men In Black II (2002) / Men In Black 3 (2012)
How Many Years Between Sequels: An even decade.
Do They Acknowledge The Gap? Yep, MIB3 is set exactly 10 years after MIB2 - the rest obviously did the series some good; the threequel went on to become the highest-grossing entry in the entire franchise.
Taking a leaf out of the Back To The Future series' book, MIB3 sees Agent J (Will Smith) travelling back to the '60s to fight evil alien criminal Boris the Animal (Jemaine Clement). Groovy.
The Sting (1973) / The Sting II (1983)
How Many Years Between Sequels : 10 years.
Do They Acknowledge The Gap? Sort of but not really. This sequel changes all of the first names of the lead characters (and recasts them, obviously) while also retroactively amending some of the events of the first film.
Weirdly, nobody seemed to mind - the film received positive reviews and even earned an Oscar nomination for its musical score.
" The Sting II is inspired by and is an expansion of the first Sting , rather than a continuation," explained director Jeremy Kagan.
The X-Files: Fight The Future (1998) / The X-Files: I Want To Believe (2008)
How Many Years Between Sequels: An 'Even Steven' 10 years.
Do They Acknowledge The Gap? Time has definitely passed when we catch up with Agents Mulder (David Duchovny) and Scully (Gillain Anderson).
It's been six years since the TV series ended and a decade since they were last on the big screen together, which means we get a standalone supernatural thriller co-starring (perhaps most bizarrely) Billy Connolly.
Toy Story 2 (1999) / Toy Story 3 (2010)
How Many Years Between Sequels: A toy-troubling 11 years.
Do They Acknowledge The Gap? Unlike most animated sequels, Pixar actually acknowledge the passing of time with their third toy story.
Now, Andy has grown up, and in the process he's outgrown the likes of Woody (Tom Hanks) and Buzz (Tim Allen). As he prepares for college, he also prepares to dump his one-time best buds.
The sequel gap didn't stop audiences welcoming the toys back with open arms - Toy Story 3 was the highest-grossing film of 2010 and the first animated movie to cross the $1bn threshold.
Scream 3 (2000) / Scream 4 (2011)
How Many Years Between Sequels: 11 stab-free years.
Do They Acknowledge The Gap? Well, the fourquel's tagline read 'New decade, new rules', so it at least acknowledges that 10 years have passed, if not the full 11.
Not that things have exactly changed much for the residents of Woodsboro, especially when perennial survivor Sidney Prescott (Neve Campbell) returns on the last leg of her book tour.
Cue a return, also, for the murderous Ghostface, who this time seems to be following the rules of movie remakes.
Terminator 2: Judgment Day (1991) / Terminator 3: Rise Of The Machines (2003)
How Many Years Between Sequels: A time-warping 12 years.
Do They Acknowledge The Gap? Of course - the entire franchise is predicated on the carefully-adhered-to timeline that James Cameron kicked off with 1984's The Terminator.
T3 is just the next stop in the life of John Connor, who was a 10-year-old in T2 and is now a twenty-something living off the grid (played by Nick Stahl).
Even the T-800 has somehow aged, an issue Schwarzenegger addressed recently when he argued that "the Terminator's flesh ages, just like any other human being's flesh". Alright, Arnie, if you say so.
Clerks (1994) / Clerks II (2006)
How Many Years Between Sequels: A slovenly, meandering 12 years.
Do They Acknowledge The Gap? Pretty much, though it rounds that 12 years down to an even 10, mostly so that the characters can complain that an entire decade's gone by with nothing changing.
Until, that is, the Quick Stop convenience store burns down and Dante (Brian O'Halloran) and Randal (Jeff Anderson) are forced to get new jobs. Oh life…
Muppets From Space (1999) / The Muppets (2011)
How Many Years Between Sequels: A fuzz-free 12 years.
Do They Acknowledge The Gap? Not only do star/writer Jason Segel and director James Bobin acknowledge that gap, they also acknowledge the fact that the Muppets are no longer the kings and queens of fuzzy comedy that they used to be.
It's a brave move that instils The Muppets with pathos to spare for a nostalgic ride in which Kermit attempts to reunite the separated Muppet Show players in order to save the Muppet Studios.
The next sequel, Muppets Most Wanted , only took three years to get made…
Exorcist II: The Heretic (1977) / The Exorcist III (1990)
How Many Years Between Sequels: A spooky 13 years. (Really, what are the chances?)
Do They Acknowledge The Gap? The Exorcist III is actually set 15 years after the first film (though 17 years have passed in real-time), completely ignoring the much-maligned Exorcist II: The Heretic.
Written by William Peter Blatty, E3 returns the series to its sinister roots, picking up with copper William F. Kinderman (George C. Scott) as he investigates the murder of a 12-year-old boy.
Bizarrely, the film had to be reshot to include an actual exorcism at the climax…
Basic Instinct (1992) / Basic Instinct 2 (2006)
How Many Years Between Sequels : 14 years.
Do They Acknowledge The Gap? Just about - Catherine Tramell (Sharon Stone) references Nick (Michael Douglas) from the first film, and not just when referring to the pair's mattress antics.
This time set in London, the saucy sequel finds Tramell again attempting to get her jollies at the expense of the law - and the men she casually seduces and then does away with.
It's silly, tasteless tosh.
Jurassic Park III (2001) / Jurassic World (2015)
How Many Years Between Sequels: A ground-stomping 14 years.
Do They Acknowledge The Gap? Though details of Colin Trevorrow's fourquel remain wreathed in mist, the director has revealed that Jurassic World will actually be set 22 years after the events of the first Jurassic Park.
Which fits timeline-wise, given JP3 was set (or, at the very least, released) eight years after Spielberg's original 14 years ago...
Other things we know: Chris Pratt, Bryce Dallas Howard and Vincent D'Onofrio have been cast, with the only franchise returnee being B.D. Wong (he played Dr Henry Wu in the first film).
Escape From New York (1981) / Escape From LA (1996)
How Many Years Between Sequels: A nice, even 15 years.
Do They Acknowledge The Gap? They do - whereas the first film was set in the future 1997, the sequel takes place mostly in the 'future' 2013 (Gosh, time flies).
In a Los Angeles savaged and separated from the US by an earthquake, Snake Plissken (Kurt Russell) is again called upon to save the day, this time tracking down a doomsday device in LA.
Drunken Master (1978) / Drunken Master II (1994)
How Many Years Between Sequels: A sozzled 16 years.
Do They Acknowledge The Gap? Not really - Drunken Master II is a Drunken Master film in name alone.
The plot is completely unrelated to the original film, instead following Wong Fei Hung (Jackie Chan), who's torn between his father's pacifist beliefs and his desire to stop thieves from getting their hands on precious goods.
The Godfather Part II (1974) / The Godfather Part III (1990)
How Many Years Between Sequels: 16 years.
Do They Acknowledge The Gap? Yep, it's set in 1979 (bizarrely, just five years after the first film was actually made, though that film was set between 1945 and 1955).
Godfather III brings things full circle by transforming former young go-getter Michael Corleone (Al Pacino) into an aging Don, echoing the role of Marlon Brando in The Godfather.
This time around, Michael takes a new protégé and trains him up to become his successor. This isn't going to end well…
Rocky V (1990) / Rocky Balboa (2006)
How Many Years Between Sequels: 16 years.
Do They Acknowledge The Gap? Yup, the sixth entry in the boxing box office botherer finds Rocky (Sylvester Stallone, king of the belated sequel) now in his fifties and retired from the ring.
Stallone, who wrote and directed the film, admitted he wanted to make-up for the less-than-stellar Rocky V . And after Rocky's comeback became a runaway hit, he's already talked about a seventh film - though that was eight years ago…
Dirty Dancing (1987) / Dirty Dancing: Havana Nights (2004)
How Many Years Between Sequels: A corner-dodging 17 years.
Do They Acknowledge The Gap? Do they heck. Havana Nights would rather imagine that the classic first film doesn't even exist, recycling the same plot in a modern setting (uh, Cuba).
Critics weren't kind to Guy Ferland's film, branding it "cheesy" and "unnecessary".
What would Baby think?
Halloween II (1980) / Halloween: H20 (1998)
How Many Years Between Sequels: A nightmare-inducing 18 years.
Do They Acknowledge The Gap? They acknowledge the gap and they also ignore all the other Halloween sequels, installing H20 as the first 'sequel proper' to Halloween II.
You can tell it's a 'sequel proper' because it was (at the time) the only sequel after the second to star Jamie Lee Curtis as Laurie Strode.
H20 benefits greatly from her presence, discovering her still traumatised by the events of her past and giving her the chance to put her demons to bed once and for all. If only Halloween: Resurrection had never happened…
Indiana Jones And The Last Crusade (1989) / Indiana Jones And The Kingdom Of The Crystal Skull (2008)
How Many Years Between Sequels: 19 years.
Do They Acknowledge The Gap? They sort of have to, considering Harrison Ford's back as fedora-wearing hero Indiana Jones - 20 years sort of change a person's face.
Not that that stops Jones from getting in on the action. Except this time the explosions, giant leaps and fist fights come equipped with a 60-year-old Indy complaining about his aching back…
Rambo III (1988) / Rambo (2008)
How Many Years Between Sequels: 20 years.
Do They Acknowledge The Gap? Yep, the much-belated fourth entry in John Rambo's (Sylvester Stallone) PST action saga kicks off exactly 20 years after the Soviet war in Afghanistan.
This time, the action shifts over to Burma, where Rambo dons the bandana once more to help rescue a group of church missionaries.
Which is when things get really, REALLY bloody. You thought the other films had blood? Just check out Rambo …
Psycho (1960) / Psycho II (1983)
How Many Years Between Sequels: 23 long, long years.
Do They Acknowledge The Gap? Just about - Psycho II is actually set 22 years after the events of Hitchcock's first film, so it's just a single year shy of the actual time period that has elapsed.
The plot sees Norman Bates (Anthony Perkins, looking considerably older) released from a mental institute and returning to his home, where he starts to go a little mad again.
This time in Technicolor.
Carrie (1976) / The Rage: Carrie 2 (1999)
How Many Years Between Sequels : 22 years.
Do They Acknowledge The Gap? "I had a traumatic experience in high school. I tried to help someone, and it backfired horribly," says Sue Snell (Amy Irving), the only character to return after (and, seemingly, remember the events of) the first film.
A Gothed-up rinse and repeat of the first film, Carrie 2 follows outcast Rachel (Emily Bergl), who may be able to move things with her mind when she's angry.
Well, it's better than the remake, at least.
Wall Street (1987) / Wall Street: Money Never Sleeps (2010)
How Many Years Between Sequels: 23 years.
Do They Acknowledge The Gap? To the year; Oliver Stone's belated follow-up acknowledges every one of the 23 years that have elapsed since Gordon Gekko (Michael Douglas) first rained terror down on New York.
In the sequel, Shia Labeouf plays the fiancé of Gekko's daughter (Carey Mulligan), repeating the trick he played with other belated sequel Indiana Jones And The Kingdom of The Crystal Skull.
Weirdly, this time around Gekko's more of an anti-hero than a villain. He's clearly mellowed with age…
The Hustler (1961) / The Color Of Money (1986)
How Many Years Between Sequels: 25 years.
Do They Acknowledge The Gap? Just about. Martin Scorsese's winning drama is actually set 20 years after The Hustler, which is in keeping with the sequel novel (by Richard Price) that the film's based on.
Paul Newman returns as pool extremo Fast Eddie, one of just a handful of actors to reprise a role over two decades after first playing it.
In Money , he trains Tom Cruise's fiery, pool-playing whippersnapper (remember when Cruise was a whippersnapper?) - and Newman landed an Oscar for his troubles.
Tron (1982) / Tron: Legacy (2010)
How Many Years Between Sequels: A gob-smacking 28 years.
Do They Acknowledge The Gap? Ish. The film actually takes place 20 years after the film, though it's been nearer to 28 years since Kevin Flynn (Jeff Bridges) first disappeared into his computer and discovered the Grid.
In Legacy , his son Sam (Garrett Hedlund) goes searching for his father and finds himself similarly pixelated - and discovering Kevin's become a pseudo-Jesus figure on The Grid.
Mad Max Beyond Thunderdome (1985) / Mad Max Fury Road (2015)
How Many Years Between Sequels: A post-apocalyptic 30 years.
Do They Acknowledge The Gap? We imagine the film will acknowledge that SOME time has passed, but definitely not 30 years - anti-hero Max Rockatanasky has been recast with Tom Hardy tagging the role from Mel Gibson.
Set in the Aussie Outback, the film sees Max coming across a band of road warriors led by the fearsome Imperator Furiosa (Charlize Theron).
Star Wars Episode VI (1983) / Episode VII (2015)
How Many Years Between Sequels: 32 years.
Do They Acknowledge The Gap? Alright, this is sort of a cheat, considering George Lucas actually filmed the first of his Star Wars prequels in 1999, 16 years after he wrapped on Return Of The Jedi.
The first 'sequel proper' to Jedi , though, isn't due until 2015, which means we'll be picking up the plot with (it's assumed) Luke, Leia and Solo (plus a bunch of new characters) over 30 years later. Impressivo.
The Wicker Man (1973) / The Wicker Tree (2011)
How Many Years Between Sequels: 37 years.
Do They Acknowledge The Gap ? Though it was advertised as a 'companion piece' to The Wicker Man , it's clear that the makers of The Wicker Tree intended it as a sequel - just look at the burning imagery on the film's poster and, of course the title.
Giving nods back to Man (and thereby acknowledging the gap), the film shifts the location to Scotland where gospel singer Beth (Brittania Nicol) and her boyfriend attempt to spread the word of God.
The Wizard Of Oz (1939) / Return To Oz (1985)
How Many Years Between Sequels: A head-spinning 46 years.
Do They Acknowledge The Gap? As if. Instead of portraying Dorothy (Judy Garland) as an old lady, Return To Oz picks up just six months after the first film, with Fairuza Balk playing Dorothy instead.
Despite the massive gap between the films, Return To Oz was considered just as good as the classic original, with Dorothy again ending up in Oz.
New terrors the formidable Wheelers were just as terrifying as the Flying Monkeys.
Bambi (1942) / Bambi II (2006)
How Many Years Between Sequels: A whopping 64 years, the world record for most-belated sequel.
Do They Acknowledge The Gap? Nope - Disney act like not a single year has passed since Bambi lost his mother and was ordered to man up by the Stag.
In fact, the sequel's set during the events of the first Bambi , with the wobbly little doe taken into the care of the Great Prince.
Critics weren't bowled over - the film only holds a 50% fresh rating at Rotten Tomatoes.
