Malvern was born June 28, 1902 in Portland, Oregon.[1] He began his career as a member of his family's acrobatic troupe and performed in vaudeville beginning at age four, when he was touted as "the greatest child acrobat on the American stage."[4] His family's troupe toured internationally, performing as a featured act with the Ringling Brothers circus.[4]
In Los Angeles, Malvern's first work in film came as a double for Mary Pickford, and he soon began performing stunts.[5] His first major stunt appearance was doubling for Eileen Sedgwick in Beasts of Paradise (1923).[1] In 1928, Malvern suffered serious injuries in a 70 feet (21 m) fall, and he retired from stunt performing, subsequently working as a producer for Universal Pictures and Monogram.[1] Malvern married his wife Jean Huntley in 1932 and remained with her until her death in 1979.[6]
