In films, his roles were typically small and often uncredited. Among his most famous credits are "The Hustler," "Making Mr. Right" and "Let It Ride." Mr. Raymond may have achieved his most lasting notoriety as the voice of various popular cartoon characters of the 1950's. He voice the slow-witted, giant cartoon duck Baby Huey, the mouser Catnip—both creations of Harvey Comics—and the mischievous twin magpies Heckle and Jeckle. Mr. Raymond was also an adept mimic who could ape the voices of stars like Edward G. Robinson and Jerry Lewis.
