In an interview published in "Movietone News" 66-6, March 1981 (republished in Parallax-View, September 12, 2009), Strother Martin stated, “ never says so, but he cast me in Butch Cassidy. I wasn’t told until during "Slap Shot", the director said … Back when they were getting ready to do Butch, George Roy Hill said, “I’ve got these three people for Percy Garris: Strother Martin” and Paul said, “Don’t go any farther.” But he never mentioned that to me, he never said “I got you this job.” Strother Martin can also be seen in Cheech and Chong's "Up in Smoke" (1978) as Arnold Stoner, the father of Tommy Chong's character Anthony.
