10 TV Show Episodes You Can No Longer Watch

Returning to the anything but reliable BBC archives, the British Broadcasting Corporation's frustrating policy of wiping footage to make way for newer content back in the day ultimately led to a decent amount of old school Doctor Who episodes being lost forever.

Among these many discarded tapings was none other than the show's first-ever Christmas Special, something that would become a beloved hallmark of the series over the years.

Going by the name of The Feast of Steven, this Christmas Day 1965 programme acted as a comic detour away from the epic tale being told coming into the episode, with the first Doctor William Hartnell even taking a sonic screwdriver to the fourth wall in the final scene and bizarrely telling folks at home, "Incidentally, a happy Christmas to all of you at home."

Outside of the odd photograph being preserved of the showing in question, though, this surreal holiday treat appears to have been pretty much erased forever.
