I've checked some through some old answers but most seem to point towards everyones favourite film but if you had to name your top ten films what would they be, to start the ball rolling mine are, in no particular order
Stand by Me Life of Brian Sin City Platoon Back to the Future (1,2,+3, taking them as 1) The Goonies The Inside Man (If you haven't seen it, it is superb) The Butterfly Effect (I know Ashton Kutcher is in it but it's still very original, unless you saw Donnie Darko first which I didn't) The Breakast Club Being John Malkovich
From compiling this list I've realised that I could have added at least 30 more classics but that'll take to long so I'll leave it at that.
Stuck On You
Crossroads
The Great Escape
Gotcha!
Austin Powers (1)
Lord of the Rings Trilogy (can't leave any of the them out)
Adam's Rib
Casablanca
Groundhog Day
Ace in the Hole
