Best known for playing next-door neighbor Roger Addison on the immensely popular 1960s sitcom "Mister Ed," Minnesota-born actor Larry Keating had a long and storied career in Hollywood. Getting his start in the business during the 1940s as a radio announcer for NBC, Larry then moved to ABC where he served as the narrator of the long-running serial "This is Your FBI." By 1953, he had already appeared in over 30 movies, including the Howard Hawks-directed comedy "Monkey Business," starring Cary Grant and Marilyn Monroe. But it was his turn as neighbor Harry Morton on "The George Burns and Gracie Allen Show" that really launched his career. Taking over the role from Fred Clark, Larry would be the last to play Morton; the "The George Burns Show" spin-off series was cancelled after only one season. But it didn't take him long to find another full-time gig: after appearances in the star-studded comedies "Who Was That Lady?" and "Boys' Night Out," Larry joined the cast of "Mister Ed" for what would be a nearly three-season run. His role as Admiral Spewter in "The Incredible Mr. Limpet," a hybrid of live action and animation, would be his final film performance. The well-respected actor died of leukemia at the age 66.
