Visual Effects Promo Film Edit
In the early 1970s the BBC's Visual Effects Department put together a showreel. This 6-minute excerpt features model effects filming from the Doctor Who stories 'The Ambassadors of Death' and 'Inferno', a watertank sketch from 'Marty Amok' featuring Marty Feldman, model shots from 'The Caves of Steel' and the filming of the forced-perspective model pier for the explosive finale of the missing 'Doomwatch' episode, 'Survival Code'. (6'02")
Deleted Scene Edit
A short deleted scene which was never seen in the original BBC transmission of the story, featuring a rather too obvious Jon Pertwee as the voice of a radio presenter. Although this scene features in the overseas versions of the story and in previous VHS releases, it was decided to remove it from the episode and present it separately in order to be truer to the UK transmission. (1'58") (1970)

The Doctor Who Annual 1971 Edit
