the pilot episode was the subject of a view-master reel and booklet set in 1968 (gaf packet # b494). one notable difference between the aired episode and the reel set is an image of the "spindrift" flying through the giant forest in apparent daylight. in the aired episode, the "spindrift" arrives on the giants' planet during the night, and its flight through the forest also occurs that same night. though the following is unconfirmed, either the daylight shot was a special effects sequence cut from the aired pilot, or a special setup for the view master photographers.
