That is the version Piven himself prefers , of course -- the kid who was on stage from the age of eight but only decided in college that he wanted to go into the family business ( his parents founded the highly regarded Piven Theatre , whose alumni include John and Joan Cusack , Aidan Quinn and Rosanna Arquette ) , then slogged his way through endless auditions , rejections , bit parts and " breakout parts " that didn 't quite live up to their promise .
