The film concerns Starman's efforts to save the Earth from the followers of Balazar, an evil genius from the planet Zemar whose prodigiously overdeveloped brain has been preserved after his own assassination.
American adaptation
The nine Super Giant films were purchased for distribution to U.S. television and edited into four films by Walter Manley Enterprises and Medallion Films. The three original Japanese films which went into Evil Brain from Outer Space were 45 minutes, 57 minutes, and 57 minutes in duration respectively. The total 159 minutes of the three films were edited into one 78-minute film. Since the three original films were self-contained stories, three different plots had to be edited together, and a considerable amount of all three films dropped. The result has been called, "an alternately mind-blowing and mind-numbing adventure...a non-ending cavalcade of characters, chases, captures, rescues and fight scenes." Contributing to the difficulty of editing these three films together was the fact that the first one of the Japanese films was in the older 4:3 ratio, while the latter two films were shot in widescreen format. This would have necessitated the use of pan-and-scanmethods to make the three films match. One of the films was also shot in color, so the footage would have had to have been converted to black and white in order to match the other two episodes.
DVD releases
Evil Brain from Outer Space is currently available on two DVD releases. Something Weird Video with Image Entertainment released the film and the other Starman film, Attack from Space on a single disc on December 10, 2002. Alpha Video also released a budget-priced disc of the film by itself on July 27, 2004. The film is also available on two multi-film compilations from Mill Creek Entertainment: Nightmare Worlds and Pure Terror.
