Actor Edward Norton has been a favorite guest on The Treatment since his breakout performance in the 1996 thriller 'Primal Fear.' Since then he has steadily surprised audiences in films including 'American History X,' 'The Incredible Hulk,' and 'Fight Club.' He has four Oscar nominations, a Golden Globe win for 'Primal Fear,' and has also directed the films 'Keeping the Faith' and 'Motherless Brooklyn.' 

His latest role is in the Olivia Wilde directed comedy 'The Invite,' which co-stars Wilde, Penelope Cruz, and Seth Rogen. Norton talks about why his characters often have a secret, how Wilde set herself apart as a director, and why 'The Invite' is the best double date film of the summer.
