Mission: Impossible is the classic television espionage series that ran on CBS from 1966-1973. From Season 2 until the series' conclusion, the team was led by Jim Phelps (Peter Graves), who assembled a team of highly specialized agents each week to accomplish a mission that no one else would dare attempt.
