Actor: Jon Favreau

Jon Favreau wrote and starred in Swingers as a vehicle for himself and Vince Vaughn, playing a man whose self-doubt is the entire subject.

Happy Hogan across the Iron Man and Spider-Man films is the recurring role, a character he wrote larger for himself as director and then kept playing.

Chef, which he also wrote and directed, is the best acting he has done, and Rudy and Deep Impact fill out the earlier work. The directing career is covered separately.
