Filming took place in late 1988, but the film sat unreleased for several years. It was first released in Europe prior to its release in the US.
Was originally set to be released by New Century Entertainment which had released the original Gate, but was later sold to Vision International after New Century closed its doors.
The film was originally rated "PG-13" just like the original film but scenes of drug use were added to be re-rated "R" by the MPAA to make the film look more appealing to horror fans.
