The title Gewaltopia Trailer has a dual meaning in the Japanese language; one meaning for the word yokoku (trailer) could mean a compilation of extracts to promote a film, but it can also mean a prediction, a prophecy for the future as a Gewaltopia. The film accumulates footage from his earlier films and arranges them in different contexts, a characteristic style of Jonouchi's who often re-edited his films for each screening and provided different soundtracks.
