Jack Kirk on AllMovie

On screen from the late '20s, roly-poly B-Western and serial perennial Jack Kirk (born Kirkhuff) began turning up in low-budget Westerns after the advent of sound, usually as a member of various music constellations bearing names like "Range Riders" and "Arizona Wranglers." He later essayed scores of scruffy-looking henchmen and, as he grew older and more settled, began playing bankers, sheriffs, and ranchers. Under term contract with B-Western industry leader Republic Pictures from July 12, 1943, to July 11, 1944, Kirk found roles increasingly more difficult to come by thereafter and left films in 1948 to work on a fishing vessel in Alaska. The former actor reportedly died of a massive heart attack while in the process of unloading a night's catch.
