40. Aw, sheet!
The movie: American History X (1998)
The mistake: At the end of the film, Danny (Edward Furlong) is shot to death in a bathroom, and drops a rolled up piece of paper in the process. When we get the close-up of dead Danny, though, he’s still clutching the paper. Magic!
How noticeable is it? Eh, with all the bloodshed and general tragedy, you probably didn't spot it.
39. Animal magic
The movie: Toy Story 2 (1999)
The mistake: Rex (Wallace Shawn) is watching TV when Hamm (John Ratzenberger) turns it off. But the shot of the switched-off TV doesn’t contain a reflection of the two toys stood in front of it. Spooky.
How noticeable is it? I’ve never noticed before because I was giggling too much at Hamm.
The movie: Leon (1994)
The mistake: When Leon (Jean Reno) helps Mathilde (Natalie Portman) flee from the SWAT team, he shoots at a vent in order to escape. But depending on which shot we’re looking at, the bullet holes change places.
How noticeable is it? Eh, it's not that noticeable if you’re caught up in the urgency of the scene, and you totally are at this point.
37. Moley moley moley
The movie: Titanic (1997)
The mistake: This one can be detected throughout the whole film. Depending on the shot, Rose’s (Kate Winslet) mole keeps switching sides on her face. It's a little like that scene in Austin Powers In Goldmember.
How noticeable is it? This is the sort of thing picked up if you were staring intently at the porcelain skin of Winslet. So, Winslet fans notice it.
36. Drop the bass
The movie: Apocalypse Now (1979)
The mistake: As Playmate Carrie Foster is escorted out by a couple of Green Berets, the bass player behind her stops playing to scratch his head – which strangely doesn’t interrupt the sound of the bass on the audio track.
How noticeable is it? To be honest, it's not particularly noticeable when you’ve got Carrie Foster in the foreground wearing the world's shortest shorts.
35. Cowboy out of time
The movie: Pirates of the Caribbean: Curse of the Black Pearl (2003)
The mistake: During a scene aboard the Pearl (the one where Depp gripes: “On deck, you scabrous dogs”), a crew member is clearly visible over Depp’s shoulder. He’s wearing a distinct outfit that's not exactly keeping with the time period: a cowboy hat and sunglasses. D’oh.
How noticeable is it? Not massively on account of Depp’s own giant hat taking up much of the frame.
34. Face the music
The movie: Chicago (2002)
The mistake: In the final major sequence of the film, Roxie (Renée Zellweger) and Velma (Catherine Zeta-Jones) are dancing on stage with machine guns. When they turn to fire at the back screen, suddenly they’ve switched sides.
How noticeable is it? Chicago’s nothing if not about choreography, so this one’s a pretty huge oversight.
33. Sparkle motion
The movie: Twilight: Eclipse (2010)
The mistake: Vampires sparkle in sunlight, right? If Twilight ’s taught us anything - in addition to the gloominess, fit’s that.So why at the end of Eclipse , as Bella (Kristen Stewart) and Edward (Robert Pattinson) are sat in a sunny field, is he sparkle-free?
How noticeable is it? If you’re either a) a Twihard, or b) someone who pays close attention to mythology, you should definitely have noticed this.
32. Storm the secretary
The movie: X-Men 2 (2003)
The mistake: The President is visited by the X-Men, and his desk is clearly covered in spread-out papers. Until the mutants disappear and he’s suddenly got a neat blue folder in front of him. I blame pesky old Storm.
How noticeable is it? Considering the folder is bright blue – like a fair few X-Men mutants – that bad boy really stands out.
31. The Goblet of Shrimp
The movie: Ocean's Eleven (2001)
The mistake: In the Botanical Gardens, Rusty (Brad Pitt) is enjoying a lovely bowl of shrimp. Until the next shot, when he’s suddenly got a plate of shrimp.
How noticeable is it? Seeing as how Rusty's constant eating in the movie is referenced often, this one's kind of a biggie.
