Steve Martin made his film-starring debut in this wild and crazy comedy hit The Jerk. Steve portrays Navin Johnson, adopted son of a poor black share cropper family, whose crazy inventions lead him from rags to riches and right back to rags. Along the way, he s smitten with a lady motorcycle racer, survives a series of screwball attacks by a deranged killer, becomes a millionaire by inventing the Opti-grab handle for eyeglasses and shows why he s still one of the best comic performers.
