Jonah Hill (born December 20, 1983) is an American actor and screenwriter. Hill has had a successful career as an actor in comedic films, appearing in roles in the films Accepted, Grandma's Boy, Knocked Up, Superbad, Walk Hard, Strange Wilderness, and Forgetting Sarah Marshall.

Hill was born Jonah Hill Feldstein to Jewish parents in Mill Valley, California, and attended Brentwood School and then Crossroads School, in Santa Monica. After graduating from high school, Hill left California to attend school at New School University, where he studied acting. He also attended the University of Colorado at Boulder for one semester as a freshman after having left New School University.

In college, Hill began writing his own plays and performing them in the Black and White bar in the East Village neighborhood of New York City. His plays developed a small following and helped him realize that his true desire was to act in films. Hill was befriended by Dustin Hoffman's children, Rebecca and Jake, who introduced Hill to their father. The elder Hoffman asked him to audition for a role in I Heart Huckabees, in which Hill made his film debut. Hill made a brief appearance in Judd Apatow's directorial debut The 40-Year-Old Virgin, which eventually led to him starring in a larger supporting role in the Apatow-produced Knocked Up and the lead role in the Apatow-produced Superbad. Hill also played the "RA Guy" on the first season of the Oxygen Network sitcom Campus Ladies.
