Bob Johnson (actor) Robert Cleveland Johnson (May 4, 1920 – December 31, 1993), known professionally as Bob Johnson, was an American actor and voice actor who played supporting roles on series television and in films from the late 1950s until a few years before his death. He frequently provided the voices of numerous alien creatures on "The Outer Limits"—including the episode "The Guests"—for which he was uncredited.
