Burkex, you are forgetting one of Hanks best movies. it was called Nothing in Common, made in 1986. his father (played by jackie gleason) just divorced from his mom who left him and hanks has to deal with both mom and dad's situation and take on his own problems. its a very serious movie and it came out before big and A League. That movie had me crying my ass off when i saw it on cable 20 years ago.
Tom Hanks
Lets also not forget his serious role in Mazes N Monsters (1982) as a mildly crazy DnD addict.
