These special effects storyboards were drawn for the episode Missing Link. Several of these shots have filming dates in early May 1974. In July 1974 a new script would be produced, and additional effects shots were made (see here).
The SFX scene list, dated 6th May 1974, marked as "Amendments". The live action filming in Pinewood had just finished (on 3rd May), but there had been numerous script changes. The original script opening had been filmed on 2nd and 3rd May, but on 3rd May a new opening was published, cutting out a lot of the action. This SFX scene list is based on that 3rd May opening.
Some of the SFX shots storyboarded below were filmed on 2nd May, but were fortunately unchanged by this version of the script.
A third new opening would be written on 5th July, and filmed on 22nd July. Those new SFX scenes are described later
There were seven storyboard pages for the original version of the episode, which we examine shot-by-shot in the following pages.
Scene 1A.
Eagle approaches out of control.
Filmed on 6th May 1974. Originally the second shot of the episode, new scenes would be inserted before this one.
