Trivia: To make the robot in the movie, first they used a small puppet and had the puppeteers under the floor controlling it through sticks. To make the huge robot, they had a "bam bot" for ramming through walls and windows, a technical robot that had all the circuitry to make the antennae move and the nose to steam,and a version where there were only the feet and the body (they would later animate the arms and legs.) The robot was more mechanics than electronics.
Question: When Danny presses the button, the red spaceship moves onto a white space. Later in the movie, after accepting the astronauts' help, all three discover that the red spaceship is now on a blue space. How could it have gotten there? Neither Danny or Walter kicked the board and Danny never actually moved it from its original position since they had to deal with getting rid of the Zorgons.
