Trivia: Alan Oppenheimer is one of the busiest of that breed of character actors who so expertly blend into the roles they're playing that they don't seem to be acting at all. Generally cast in "management" roles in films (the chief supervisor in 1973's Westworld, for example), Oppenheimer has also been a regular or semi-regular on several TV series. He was Dr. Rudy Wells during the first season of The Six Million Dollar Man (1974-75) ex-gangster Sheldon Leonard's brother Jessie on Big Eddie (1975), Captain Finnerty on Eischeid (1979-83) and Ben Brookstone on Home Free (1993), and was seen on an occasional basis as Dr. Raymond Auerbach on Murder She Wrote and network president Eugene Kinsella on Murphy Brown. Alan Oppenheimer's most lasting legacy rests in his innumerable cartoon voiceovers for Hanna-Barbera, Filmation, Disney and other studios: He was heard as Ming the Merciless on New Adventures of Flash Gordon (1979), Sidney Merciless in the "Shake Rattle and Roll" component of CB Bears (1977), Mighty Mouse in The New Adventures of Mighty Mouse and Heckle and Jeckle (1979 Filmation version), Big D on The Drak Pack (1980), Tawky Tawney and Uncle Dudley in Kid Super Power Hour with Shazam (1981), Vanity on The Smurfs (1981-90), Sheriff Pudge on The Trollkins (1981), Skeletor in He-Man and the Masters of the Universe (1983), the King of Gummadon in Disney's Adventures of the Gummi Bears (1985), Colonel Trautman in Rambo (1986), Pa Kent on Superman (1988 Ruby-Spears version), Merlin in The Legend of Prince Valiant (1991), and so many others.
