In the film, when nurse Riefenstahl is all by herself in her Control Room she secretly admires a photograph of Darth Vader.
After nurse Riefenstahl's scream, when the camera zooms out to the entire planet Earth, editor Chris Heeren secretly added a TIE Fighter from Star Wars, to surprise director Vincent van den Ouden. When Van den Ouden found out he was so amused he kept the joke in the movie.
