Gravity. The part where Sandra Bullock's character was talking about how her daughter died just broke me. I have a daughter the same age and if something like that happened to her I'd want to just drift off into space too.
I've come close with many films but I've never actually cried....okay, actually, I can remember crying when I was 5 years old. My mom had let me watch Gremlins and I was scared to walk down the hallway afterwards. I was so scared that I burst into tears, but something tells me this was not the type of crying you meant ;)
It's the first movie I remember ever seeing. My family did a movie marathon, I'm pretty sure we watched three movies but I only remember Ghostbusters and Gremlins. I loved Ghostbusters, and I enjoyed Gremlins but I let me imagination run away with me after the movie was over. I kept thinking a gremlin was going to jump out of the dark and get me.
