Free Willy
UP is a brilliant suggestion on that thread. Just when you're settling in to what you think is a nice family pixar film, they hit with you with a wave of emotion.
A Beautiful Mind, esp near the end, makes one well up a little....
I've watched that film three times and it really annoys me because it portrays people with schizophrenia as having no personality and just being plain paranoid, odd and socially inept.
I can cry at Disney films!!!
I'll kick things off with Click. Yes, I know it's an average Adam Sandler film that's only moderately funny at best. But the bit with his Grandad (you'll know it if you've seen it) had me crying like a baby.
When I was a kid I cried at the end of two films:
E.T.
The Snowman
I have never lived down the latter.
As an adult the closest I have come to crying is probably Schindler's List
These 2 and Green Mile.
