US print ad and lobby cards for Galaxy of Terror featuring one of its earlier alternate titles, Planet of Horrors, said to be the original title of the screenplay for the film. Another alternate title, seen on an early trailer, was Mindwarp: An Infinity of Terror. During production, the film was also known as was The Quest, which is the name of a spaceship in the film.
The film’s alternate title, as seen on this US print ad and lobby cards, is set in Earth, which was also later used on Cameron’s The Terminator and Terminator 2: Judgment Day. Furthermore, Ernest D. Farino, who designed and later supervised the title sequences seen in the first two Terminator films, also worked on Galaxy of Terror as Graphic Animation Designer.
