There are many but 'The Goonies' and 'Lost boys' always stand out for me.
But to create a small list: Blade trilogy, star wars films (all), matrix trilogy, The crow, armour of god (jackie chan), star trek films, contact, The breakfast club, Snatch, Lock stock and two smoking barrels, Pulp fiction, WALL-E, finding nemo, Terminator films, Alien 1234, Alien vs predator, predator 1, Platoon, Full metal jacket, Stardust, Chopper, Equilibrium, Drag me to *censored*, Resident evil 123, Hangover, Akira, Drunken master (jet li), Green mile and shawshank redemption.
I had to give up there or I would have to go downstairs and look through the 250-300 DVDs I have down there.
:EDIT: oh and 'standy by me'.
