WWI-veteran Jack Pennick was working as a horse wrangler when, in 1926, he was hired as a technical advisor for the big-budget war drama What Price Glory? Turning to acting in 1927, Pennick made his screen bow in Bronco Twister. His hulking frame, craggy face, and snaggle-toothed bridgework made him instantly recognizable to film buffs for the next 35 years. Beginning with 1928's Four Sons and ending with 1962's How the West Was Won, Pennick was prominently featured in nearly three dozen John Ford films. He also served as Ford's assistant director on How Green Was My Valley (1941) and Fort Apache (1947), and as technical advisor on The Alamo (1960), directed by another longtime professional associate and boon companion, John Wayne. Though pushing 50, Jack Pennick interrupted his film career to serve in WWII, earning a Silver Star after being wounded in combat.
