Episode Notes
For each episode, the story title, writer credit and episode number blur in over footage of volcanoes and flowing lava.

Derek Newark (Greg Sutton) previously played Za in "The Cave of Skulls", "The Forest of Fear" and "The Firemaker".

The Doctor (Jon Pertwee) tells the Brigadier (Nicholas Courtney) that he was present at the eruption of Krakatoa on August 27, 1883. It was later revealed in the Doctor Who (2005) episode "Rose" that the Ninth Doctor (Christopher Eccleston) was also present at these events.

Sheila Dunn (Petra Williams) was the real life wife of director Douglas Camfield.

This episode attracted 5.7 million viewers on initial broadcast.

Episode Quotes
The Doctor: (to Professor Stahlman) Well, I'll tell you something that should be of vital interest to you.
Professor Stahlman: What's that?
The Doctor: That you, sir, are a nitwit!

Episode Goofs
In several sequences, it is clear that both Nicholas Courtney and Olaf Pooley are wearing false facial hair. While the Brigadier and Professor Stahlman have a moustache and a beard respectively, their counterparts in the parallel universe are both clean-shaven.
