Another good family movie is "Duke" about a border collie....
I just realized I could google it, Any suggestions would be helpful though.
The Legend of 1900
Stars Tim Roth as a man named 1900 who was abandoned as a baby on a cruiser liner in the year 1900 (hence his name) and raised by the crew. It is discovered that he is a piano prodigy and he spends his whole life on the ship, never daring to step out on dry land. Until he meets a new friend who encourages him to take a chance. . .
Beautiful movie, almost like a modern fairytale and the end made me bawl like a baby.
Some others that come to mind are:
Dead Poets Society
My Girl

Ordinary People
Grave of the Fireflies
Simon Birch
