Trivia: "Horror of Fang Rock" is a story set in a lighthouse on the British coast. It is therefore ironic that this should be the only Doctor Who story to be shot at the BBC's Pebble Mill TV Studios in Birmingham, as Birmingham is about as far away from the British coast as it is possible to be in England.

Visible crew/equipment: (Ep. 2) When The Doctor, Jo, and Dr. Tyler are taken into Omega's palace, in the first shot of the multiple passageways (right before Jo says that it looks like Aladdin's cave) the curved chalk actor's mark is visible on the floor, then we see it again in three following shots. Note that when they're all escorted further inside, just as Dr. Tyler comments about the matter/anti-matter not making sense, Jon Pertwee looks down, presumably to make sure he hits his mark.

The Doctor: That's the trouble with regeneration, you never quite know what you're going to get. (00:12:15)
Question: In which season and episode is Gallifrey destroyed, or is it just a shocking new plot development for the new series?





Answer: It was never destroyed on-screen; it was intact at the end of the TV movie, and destroyed by the start of the 2005 series. It was destroyed in the novel "The Ancestor Cell," but in a completely different manner to what happened in the series.
