Doctor Who: Spearhead from Space, Episode 3 (1970)

In the third episode of the four-part story "Spearhead From Space," the Doctor (Jon Pertwee) squares off against the alien Autons, who, in league with plastics manufacturer Channing, have arrived on earth as a vanguard for the invading Nestene Consciousness. Unfortunately, neither the Doctor nor his colleagues at U.N.I.T. are much of a match for the Autons, whose deadly weapons are built into their hands. Equally unfortunate is the fact that the Doctor has been denied the use of his trusty TARDIS, forcing him to deal with the enemy minus any sort of electronic assistance. First telecast January 17, 1970, "Spearhead From Space, Episode 3" was written by Robert Holmes. ~ Hal Erickson, All Movie Guide
