John Ince was the older brother of producer/directors Tom Ince and Ralph Ince. Like his siblings, John was a stage actor from childhood. Despite his huge, fleshy frame, Ince found work as a leading man when entered films in 1913; he also directed and scripted several of his own vehicles. Concentrating almost exclusively on directing from 1915 through 1928, Ince returned before the cameras as a character actor in the early years of the talkies. While many of assignments were bit roles, John Ince could always be counted on to make his scenes important; he was quite memorable as Major Bowes clone "Colonel Crowe" in the 1935 Buster Keaton two-reeler Grand Slam Opera, and as the real-life Monogram producer Sam Katzman (whom Ince resembled not in the slightest) in the Bela Lugosi chiller Voodoo Man (1944).
