Wilke was great as a villian and in later year played similar character types but in a comedic way. He started out with bit parts in "B" westerns and his final role was in Bill Murray's classic comedy STRIPES. I first remember him as Jim Pierce in HIGH NOON and later saw him, like Dehner, in almost every tv western.
Wilke and Dehner appeared several times in the same movie/tv show. Most notable was Anthony Mann's classic 1958 Gary Cooper flick MAN OF THE WEST. Dehner was Cooper's embittered cousin Claude and Wilke was Ponce another member of the Uncle Dock Tobin gang, and they were both in John Sturges' 1965 "comedy" western misfire THE HALLELUJAH TRAIL. They also were in "Incident of the Four Horsemen" a 1969 episode of RAWHIDE; THE CHEYENNE SOCIAL CLUB (1970); Tim Holt's HOT LEAD (1951); Monte Hale's OUT CALIFORNIA WAY (1946) with Roy Rogers; Rory Calhoun's POWDER RIVER (1953) and the 1946 non-western THE CATMAN OF PARIS. Wilke was unbilled as "The Catman."
Lets give these two guys their due.
