I've just remembered another weepy that I've seen (and is really powerful and emotional). It's 'Savršeni Krug' ("The Perfect Circle"). If you ever get the chance to see It, I thoroughly commend it to you (as long as you're not looking for something to cheer you up!)
I don't watch many films but I do remember Miss Potter made me cry. Theatre shows often make me cry. Blood Brothers, Miss Saigon to name just two. Also books make me cry sometimes. The Light between Oceans is very sad. I cried buckets at the end of that.
