Once the "cameos" staring doing their thing, they realized they had a movie.
Imagine Caddyshack with the main character as Danny Noonan?
To this day the "caddies" actors are not happy that most of their parts were cut.
What a drag it would be to hear the "back story" of Tony D'Annunzio.
A lot of rising stars, but in the end, the main character WAS Danny Noonan.
