Bob Johnson (born Robert Cleveland Johnson on May 4, 1920 in Portland, Oregon - died December 31, 1993 in Molokai, Hawaii) 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 he died. He frequently provided the voices of numerous alien creature on The Outer Limits -- including the episode "The Guests" -- for which he was uncredited, and may have been involved in English-language dubbing on lesser-known spaghetti westerns. However, Johnson is probably best known as the "voice behind the scenes", who gave Special Agents Dan Briggs and Jim Phelps their recorded mission briefings on both incarnations of the Mission: Impossible television series.
