Big Fish - with K here, reminded me of my old man
My Dog Skip - seriously, the ending is a real tear jerker. Based on a true story from Willie Morris growing up in Mississippi in the mid late 40s
Cinderella Man - great ending, not sad, but emotional. Great payoff at the end. Also a true story - Jimmy Braddock played by Russell Crowe wonderfully.
Forrest Gump - when Jenny dies, the grave scene, the birds fly away. You gotta feel for the guy. Hanks did that one well.
