Oh such a hard thing to limit it to ten! Let's see...
Reservoir Dogs
Clerks (and the entire Jersey Trilogy really)
Lock, Stock, and Two Smoking Barrels
Sliding Doors
Fight Club
Hackers (I just love Jonny Lee Miller and Angelina Jolie)
Memento
Underworld
Made
Boiler Room
Most people probably won't agree with my choices but anywho...
1. The Usual Suspects (I love that movie... I just do!)
2. The Green Mile
3. Shawshank Redemption
4. Casino
5. Lock Stock and Two Smoking Barrels
6. The Princess Bride (Its a kids movie but its just the finest thing ever!)
7. All "Alien" series (They really scare me even though I've seen them like 100 times!)
8. Meet the Parents (funny!)
9. Little Nicky (f**king funny!)
10. Shindlers List (moves me to tears every time... a master piece)
