Can't think of any movies I've cried at. There was I Am Sam or whatever it was, but to be fair, I had also just broken up with my girlfriend at the time.

I did cry at a TV show once. When I was about six years old or so. I remember it well - it was a documentary and was following some bears. A cub got caught on a rock in the middle of a river which was flooding and the mum couldn't get to it, and the person doing the voice for the documentary went on about how the cub was doomed or something. I couldn't understand for the life of me just why the people doing the documentary didn't do anything to help. I went and cried to mummy about it.
