Have not seen this movie, but it is interesting to note that, like Rocky, the author managed to get a part in his own movie.

Summary from IMDB

The young, handsome, but somewhat wild Eugene Morgan wants to marry Isabel Amberson, daughter of a rich upper-class family, but she instead marries dull and steady Wilbur Minafer. Their only child, George, grows up a spoiled brat. Years later, Eugene comes back, now a mature widower and a successful automobile maker. After Wilbur dies, Eugene again asks Isabel to marry him, and she is receptive. But George resents the attentions paid to his mother, and he and his whacko aunt Fanny manage to sabotage the romance. A series of disasters befall the Ambersons and George, and he gets his come-uppance in the end.
Written by John Oswalt
