The Moonbase - Episode 3 alternate ending

Episode 3 of The Moonbase over-runs by about a minute, while Episode 4 under-runs by about the same amount. Subsequent production teams would often remedy such occurrences by moving a cliffhanger forward or back, but in the 1960s more limited editing facilities preventing this.

This video demonstrates an alternate ending to the missing Episode 3 (represented by stills and audio) and an alternate opening to Episode 4, with the cliffhanger brought forward and the remaining material from Episode 3 moved to the beginning of Episode 4.
