Charles Dierkop played Flat Nose Curry in Butch Cassidy and the Sundance Kid.
While riding off the Kid tells Hannibal he "can be replaced". Of course he WAS replaced when Ben Davis took over the role of Hannibal after the suicide of Peter Duel.
Ben Davis uses the old catchphrase "I'll be a blue-nosed gopher" that Wrangler Ollie (leonard P. Greer) was known for on the old "Spin and Marty" series.
