In the script, the episode opens with two SFX shots, a shot of the sun over the moon surface, and then scene 53, "Morrow emerges from the crashed Eagle, carrying Sandra in his arms.". Both shots were either not filmed, or filmed and not used.
Scene 152
Perhaps a slight variation of 70A. Sun must be yellow.
No Alpha in shot
Repeat Sc.52
Just comments for this storyboard.
Scene 52 is the first sunrise early in the episode.
Scene 70A is the desolate moonscape when Paul and Sandra sit down outside Alpha.
Scene 153
Repeat Sc.124. - but different action
We don't have a storyboard for scene 124, but it occurs just after Carter and Paul blast open the crashed Eagle door and emerge onto the surface. By re-using one set-up, the production got two shots for the price of one.
On the shooting schedule, scene 152 is listed among the SFX shots, and scenes 124 and 153 live action are on page 4 for filming Friday 2nd August 1974. However, they do not appear on the call sheets. The similar shot for Another Time, Another Place was filmed some time after the episode at Bray, however, so they it could have still been scheduled or shot outside the main filming block.
So how would they shoot actors emerging from a full-sized Eagle? Brian Johnson wrote the word "Matte" on the SFX script, and on the back of the pages he sketched for detailed plans for the shot.
The shot is a variation of the scene where the crew leave the "full sized" Eagle for Another Time, Another Place. The Eagle is a foreground cut-out. It was filmed at Bray Studios, using stand-ins, on Monday 8th July 1974, during the filming of the episode Alpha Child.
This is the camera-framing for scenes 124 and 153. We see the Eagle from the view of the engines, with the actors centre-left, and a foreground rock on the left.
