41. The Rocky Horror Picture Show (1975)
Why It's Rewatchable: It takes several goes (in the company of an appreciative audience) to memorise all of the bits you're supposed to shout at the screen.
If You Only Rewatch One Scene: Let's do the Timewarp again.
40. Lethal Weapon (1987)
Why It's Rewatchable: The sequels steadily got too silly, but here Gibbo's goofiness and Shane Black's wisecracks are anchored in brutal 1980s action.
If You Only Rewatch One Scene: How mad is Mel? He jumps off buildings with wannabe suicides. That mad.
39. Ferris Bueller's Day Off (1986)
Why It's Rewatchable: Ferris' truancy manifesto remains pertinent whatever your age.
If You Only Rewatch One Scene: Ferris gatecrashes a carnival for a spot of Twist And Shout.
38. Shaun Of The Dead (2004)
Why It's Rewatchable: Like its predecessor, TV sitcom Spaced, Wright spends ages getting the details right. It's a treasure-trove of pop-culture in-jokes.
If You Only Rewatch One Scene: Shaun and the gang take on the zombie hordes to the strains of Queen's Don't Stop Me Now.
37. North By Northwest (1959)
Why It's Rewatchable: Hitchcock deliberately set out to make a Greatest Hits film using American monuments as set-piece staging posts, making this lighter and more accessible than most of his suspense classics.
If You Only Rewatch One Scene: The simple but surreal sight of sharp-suited Grant being attacked by a crop duster.
36. Dirty Dancing (1987)
Why It's Rewatchable: Many films show an innocent girl finding independence through true love, but none of those other girls do it by being held aloft by Swayze as The Time Of My Life plays.
If You Only Rewatch One Scene: Baby is put in a corner. Johnny isn't happy.
35. The Great Escape (1963)
Why It's Rewatchable: That effortless, everybody-gets-to-shine ensemble is perfectly constructed for lazy Bank Holiday afternoons.
If You Only Rewatch One Scene: The escape itself, if only to marvel at the fact you're involuntarily counting everybody out even though you know what happens.
34. Terminator 2: Judgement Day (1991)
Why It's Rewatchable: Cameron kept the timey-wimey head-scratching of the original, but this time had the budget to blow on bike/tanker face-offs and the mighty morphin' T-1000.
If You Only Rewatch One Scene: Arnie's definitive role gets an unexpected emotional kick as the climactic foundry battle ends with the Terminator committing cyborg suicide in the molten river.
33. Evil Dead 2 (1987)
Why It's Rewatchable: Two films for the price of one--the frenetic recap/remake of The Evil Dead, followed by the hysterical splatstick of Bruce Campbell's Ash going insane and getting groovy.
If You Only Rewatch One Scene: Ash fights his possessed hand, using a chainsaw and a copy of Hemmingway's A Farewell To Arms.
32. Ghostbusters (1984)
Why It's Rewatchable: It caters to all of your 1980s needs at once: Saturday Night Live humour, Industrial Light and Magic FX and Ray Parker Jr's mighty theme tune.
If You Only Rewatch One Scene: Ancient evil reborn in the form of a giant advertising mascot.
