Billy Wilder featured Revill in both "The Private Life of Sherlock Holmes" (1970) and "Avanti!" (1972). In the latter, Revill won critical kudos for his turn as an all-knowing, highly efficient hotel manager. In the cult classic, "The Legend of Hell House" (1973), he was the pragmatic physicist who did not believe the house was haunted but nevertheless had the gadgets to destroy the ghosts, if necessary. For director David Irving, he appeared in two features based on children's fairy tales: "The Emperor's New Clothes" and "Rumpelstiltskin" (both 1987). Revill has appeared in two Mel Brooks outings as well, "Robin Hood: Men in Tights" (1993) as the fire marshal, and "Dracula: Dead and Loving It" (1995) as Sykes.On TV, Revill's work has included such miniseries and movies as "The Great Houdini" (ABC, 1976), "Centennial" (NBC, 1978-79) and "Moviola: The Scarlet O'Hara War" (NBC, 1980), in which he portrayed Charlie Chaplin. In the TV remake of "The Diary of Anne Frank" (NBC, 1980), Revill was Mr. Dussel, the dentist, barely aware of his Jewish origins, who sought refuge with the Franks. Revill's first American series was the short-lived "Wizards and Warriors" (CBS, 1983) and he gave memorable support to David Alan Grier in the equally short-lived "The Preston Episodes" (Fox, 1995). After providing the voice of the Emperor in "The Empire Strikes Back" (1979), Revill began a second career as a voice actor working on numerous animated series including, "Dragon's Lair," "Snorks," "Pound Puppies" and "Batman."
