science-fiction films 20 Million Miles to Earth and The Deadly Mantis, released in 1957. In 1956 Hopper guest-starred again on television during the first season of the Western series Gunsmoke, portraying an outlaw initially supported by townsfolk in an episode titled "Robin Hood". The following year he played a supporting role in the pilot episode of the television series The Restless Gun, which was broadcast as an episode of Schlitz Playhouse of Stars. Some of Hopper's other television guest appearances include The Joseph Cotten Show, Fury, Studio 57, and The Millionaire. Perry Mason Hopper is best known for his principal role as the private investigator Paul Drake on CBS's courtroom television series Perry Mason (1957–66). He initially tested for the title role, while Raymond Burr read for the role of Mason's courtroom adversary, district attorney Hamilton Burger. Burr was encouraged to lose weight and return to audition for the role of Perry Mason — which he did, successfully. Hopper, too, was called back. Executive producer Gail Patrick Jackson recalled, "When Bill Hopper came in to read for Paul Drake he blurted out, 'You hate my mother.' And that was Hedda Hopper. Well, I disliked what she stood for, but 'hate' is something else — and anyway he was perfect as Drake, and we got him." Wrote Brian Kelleher and Diana Merrill in their chronicle of the television series: As Paul Drake, William Hopper was called on to be the most versatile of the principals in the Perry Mason cast. He was not only the careful investigator, the duke-it-out tough guy, the ladies' man, and the hipster, but also the fall guy, the strikeout artist, the "eating machine" and "the big kid." Hopper's Drake alone provided the comic relief for the show. And, despite being a rather late bloomer to the acting field, he played all the parts surprisingly well and believably. His appearances made fair shows good, and good shows better. A 1959 episode, "The Case of Paul Drake's Dilemma", had Hopper's character on trial for murder. Hopper continued to work in summer stock and to make movie appearances during his years on Perry Mason; however, after the series was cancelled in 1966, he declined other television offers. He did, though, make one final film appearance in Myra Breckinridge (1970), which premiered in New York three months after his death. Accolades In 1959, Hopper was nominated as Best Supporting Actor
