Trivia: Doctor Who S5 E1 "The Tomb of the Cybermen"

  • Missing Episode: Averted. Like the rest of Season 5 (and Season 4), this story was lost for decades... until 1991, when a copy of all four episodes was returned from Hong Kong of all places, along with a number of other old British TV programs. It would remain the only intact serial from Patrick Troughton's first two years until October 2013, when the discovery at a relay station in Nigeria of nine more lost episodes, all from Season 5, led to the completion of "The Enemy of the World" (only one of its six episodes was known to exist before this).
