The son of legendary actors Jason Robards and Lauren Bacall (and godson of Katherine Hepurn—impressive), Sam Robards studied acting in college and appeared in several plays off Broadway before making his feature film debut in Paul Mazursky's Tempest. He appeared alongside his father in 1988's Bright Lights, Big City and costarred with his mother in the 1993 Robert Altman film Prêt-à-Porter. His film resume also includes Casualties of War, American Beauty, A.I.: Artificial Intelligence, and The Other Side of the Tracks. He married fellow actor Suzy Amis in 1985, and they have one son. They divorced in 1993, and Sam remarried in 1997, finding love with Danish model Sidsel Jensen. They have two sons together. Important question: are Sam's sons as adorable as Nate Archibald, Sam's character's son on Gossip Girl? That's some stiff competition in the adorableness department.
