Jack Mower on AllMovie

Silent film leading man Jack Mower was at his most effective when cast in outgoing, athletic roles. Never a great actor, he was competent in displaying such qualities as dependability and honesty. His best known silent role was as the motorcycle cop who is spectacularly killed by reckless driver Leatrice Joy in Cecil B. DeMille's Manslaughter (1922). Talkies reduced Jack Mower to bit parts, but he was frequently given work by directors whom he'd befriended in his days of prominence; Mower's last film was John Ford's The Long Gray Line (1955).
