Oh of course Well I've never actually cried during a movie because I'm not a cryer but yesterday when I saw the Benjamin Button movie my eyes got very warm and it almost happen during the end of the movie when he was just a kid again and the character of Cate Blanchett took care of him.
I don't cry in movies (not because I'm a tough guy or anything; they just don't affect me that way), but if you're after some truly sad movies, check out "Dear Zachary" and "Grave of the Fireflies".
I never let tears during the movie... at least so far I didn't. But there's one movie that had me on a thin line and that's Hachi: A Dog's Tale. Fuck my ass, that's too emotional.
