Mission: Impossible is an American television series that chronicles the missions of a team of secret American government agents known as the Impossible Missions Force (IMF). The show is a continuation of the 1966–1973 TV series of the same name. The only actor to return for the series as a regular cast member was Peter Graves who played Jim Phelps, although two other cast members from the original series (Greg Morris and Lynda Day George) returned as guest stars. The only other regular cast member (unseen) to return for every episode was the voice of "The Tape" (in this series, "The Disc"), Bob Johnson.
