Tokyo Godfathers (2003)
(This is another anime, sorry.)
It's basically about three hobos who find a baby in a dumpster on Christmas eve. They then set out to return the baby to her mother, hyjinks ensue. This movie is funny, but still manages to make you ball your eyes out by the time it's over.

An overreaching theme of the movie is family. We find out why each homeless person ran away and by the end the main characters are reunited with their family one way or another.

Another good thing about the film is that one of the characters is transgender and it's played straight. No excuses like 'it's just a dude who likes wearing a dress because of ____' like a lot of anime does. The issue is treated realistically.
