My favourite movie is probably The Green Mile. It makes me cry every time
After that, probably Forrest Gump, Inception and Forgetting Sarah Marshall. There's a few more, but I can't really think of them right now. I can't say I've seen a lot of movies though.
Finally, someone else that loved Forgetting Sarah Marshall! My list from the movie thread we had a couple weeks ago:
Forgetting Sarah Marshall
Hot Fuzz
Shaun of the Dead
Pitch Black
The Lord of the Rings trilogy
40 Year Old Virgin
Anchorman
I Love You, Man
Still think I'm forgetting stuff.
