Doctor Who's record-breaking 21st anniversary was launched January 5, 1984, with episode one of the four-part "Warriors of the Deep." At the height of a 21st century Cold War, the Doctor (Peter Davison) and his companions Tegan (Janet Fielding) and Turlough (Mark Strickson) are accused of being saboteurs. This is a benign threat compared to the one posed by two of the Doctor's former nemeses -- the Sea Devils and the Silurians, last seen on
Doctor Who way back in 1972. "Warriors of the Deep, Episode 1" was written by Johnny Byrne. ~ Hal Erickson, All Movie Guide
