The Scamp (1957)

British juvenile actor Colin Peterson plays the title character in Scamp. The son of a drunken vaudevillian performer, Peterson is left in the care of a kindly professor (Richard Attenborough) and his wife (Dorothy Alison) when his father goes on a South American tour. His guardians try to get the boy to behave properly, but Peterson has been on his own for so long that he has never developed any sense of self-discipline. After running afoul of the law, Peterson is sent back to his father, who resumes his abuse of the boy. During an argument, Peterson hits his father over the head with an ashtray--and shortly afterward, the father drops dead. Convinced that he's a murderer, Peterson hides out in the professor's home. With the help of his new surrogate father, Peterson proves that his besotted dad died of a booze-induced fall. Scamp was based on Charlotte Hastings' play Uncertain Joy. ~ Hal Erickson, Rovi
