With the recent announcement of Doctor Who filming in Lanzarote alongside Moffat’s tease of the Doctor “returning to the scene of an old adventure”, speculation has gone wild.

One prominent theory is that the 12th Doctor will revisit Pompeii. This was brought on by Moffat’s tease last year where he stated that Capaldi’s past appearances in the Whoniverse will not be ignored:

“I remember Russell [T Davies] told me that he had a big old plan as to why there were two Peter Capaldi’s in the Who universe: one in Pompeii and one in Torchwood. When I cast Peter and Russell got in touch to say how pleased he was, I said, ‘Okay, what was your theory and does it still work?” and he said, ‘Yes it does. Here it is…’ “We’ll play that one out over time. It’s actually quite neat.”

Something that might support this is that filming is taking place at the Volcán del Cuervo, aka the Raven’s Volcano. The show’s make-up artist, Claire Pritchard, recently tweeted some pics of the filming base and a view of the volcano:



Then of course there’s the other theory that it could be a follow up to the 1984 Fifth Doctor adventure “Planet of Fire” which saw Lanzarote used as itself and the volcanic planet Sarn.

However, there’s conflicting earlier reports that the story will take place on the moon, with the rumoured title “Kill the Moon”. The landscape could just as easily provide suitable landscapes for that. As ever, time will tell…
