Isn't there a third brother who is also an actor?
His other brother is Micheal Penn, and his biography says he is a musician and was also in the movie Boogie Nights.
Actor Chris Penn, brother of Sean Penn, was found dead Tuesday at a condominium near the beach in Santa Monica, police said.
His late father, Leo Penn, directed television shows. His mother, Eileen Ryan, is an actress whose credits include "I Am Sam," "Magnolia" and "Parenthood." Another brother is musician Michael Penn.
