It was cut from Star Wars. The photo was a daily from the original negative and it appeared in Dr. Reynolds lost cut article. The small gentleman, nick-named "Little Flash Gordon" by the costume and make-up department, appears to be running from stormtroopers as part of the panicked crowd that the troopers march bu on their way to docking bay 94. This scene in question was an unscripted gag that they filmed and edited out. And somehow this clip ended up in the Holiday Special. It makes sense that the HS ended up using this clip as well as the one with Darth Vader and Chief Bast from the Death Star. They get to use authentic Star Wars footage that wasn't already seen in the film and they didn't have to shoot any new footage. Cheap and easy.
