The Jerk is a 1979 American comedy film. Directed by Carl Reiner, the film was written by Steve Martin, Carl Gottlieb and Michael Elias. This was Steve Martin's first starring role in a feature film. The film also features Bernadette Peters, M. Emmet Walsh and Jackie Mason. The film begins with Navin R. Johnson (Steve Martin), a homeless bum, directly addressing the camera and telling his story. He is the adopted white son of African American sharecroppers, who grows to adulthood naively unaware of his obvious adoption. He stands out in his family not just because of his skin color, but also because of his utter lack of rhythm when his adopted family plays spirited blues music. One night, he hears the staid and starchy Roger Wolfe Kahn Orchestra song called "Crazy Rhythm" on the radio and his feet spontaneously begin to move with the urge to dance; he sees this as a calling and decides to hitchhike to St. Louis, from where the song was broadcast.
