Just saw the movie Norbit today, starring Eddie Murphy. Norbit himself reminds me of the characters Eddie Murphy played on Saturday Night Live back in the 80's.
The movie is based a a character (Norbit) who was orphaned as a baby and has grown to accept companionship from those who gave it to him, then later in life realizes this is not what he wants. It is not hilariously funny but it has it's funny moments.

Although rated PG-13 the movie has alot of cursing. Take this into consideration if taking younger children.
