(written from a Production point of view)
Charles Dierkop (born 11 September 1936; age 85) played Morla in the Star Trek: The Original Series second season episode "Wolf in the Fold". He filmed his scenes between Tuesday 27 June 1967 and Monday 3 July 1967 at Desilu Stage 9 and Stage 10.
Hailing from the renowned Actors Studio, he is probably best known to movie audiences for his appearances in George Roy Hill's Butch Cassidy and the Sundance Kid and The Sting. The first featured Jeff Corey, Ted Cassidy, Kenneth Mars and Don Keefer, while the latter had Ray Walston and James Sloyan in the cast. Among his other television guest appearances was a 1966 episode of The Man From U.N.C.L.E. ("The Off-Broadway Affair"). Dierkop also appeared in an unsold 1965 television pilot titled The Long Hunt of April Savage, starring Robert Lansing and produced by Gene Roddenberry. He starred in the TV movie Murdock's Gang (1973, with William Daniels).
His later filmography included a role in Silent Night, Deadly Night (1984, with Lilyan Chauvin) and Merchants of Venus (aka A Dirty Little Business; 1998, with Robert Easton, Michael Pollard and Helen Cates).
