I was actually thinking about this last night!
1) Die Hard-The story, the action, the Bad assery of John McClain. The best in a phenominal series.
2) The Good, The Bad, And the Ugly-I'm not a connisuer of Westerns, but this one is great! For a film with so little flair, it never dulls. Clint Eastwood is great.
3) Starsky and Hutch-Loved the humor, action, instant one-liner classics.
4) Gladiator
5) Remeber the Titans- Simply a classic
6) Rocky IV-Love the cultural battle between the powerhouse nations. Also, the mountain workouts are intense.
7) Forrest Gump- So many historical references. Love it.
8) Gone in 60 seconds- that 45min chase in the mustang is a classic.
9) Toy Story- Phenominal for it's time. Started a revolution in non-real time movies
10) Run Lola Run- The German equivalent to groundhog's day. Pretty interesting.
11) Waterboy-H2O
12) Incredibles- Clever, imaginative, fun.
13) Wolverine-B/C I'M SUPER BIASED
14) Dark Knight- Perfect portrayal of Gotham mayhem. RIP Heath Ledger
15) lion King- EPIC
16) Die Hard Live Free or die hard- Bruce Willis never dies
17) Vision Quest- The only legitimate(real)wrestling movie.
18) Sixth Sense
19) Anchorman- I'm in a glass case of emotion!
20) Big Lebowski
21) Duck Soup-Old Old Old school movie with the Marx brothers. Pretty freakin hilarious. If you can find it, watch it.
22) Monty Python and the holy grail-not for everyone, but a classic.
23) Saving Private Ryan
24) Tommy Boy
25) Rudy
Haven't seen inception or toy story yet.
