The VHS cassette released by Media Home Entertainment in the 1980s and the remastered 1999 New Line Home Video release features a different song in the beginning instead of Dokken's "Into the Fire." The 'unknown' song heard is "Quiet Cool" by Joe Lamont and substituted in place of the Dokken song. The US DVD re-instates the original song back into the film.
On the first VHS release, the music video for the film's title song "Dream Warriors" by Dokken appears after the closing credits.
In the original version of the film (theatrical release and video), the nurse takes off her uniform and she's topless. In the TV version she's wearing a bra.
Banned twice in Sweden (running time 93 and 92 min). Finally passed at 90 min in 1988.
In the TV version, in the scene where the words "Come And Get Him, Bitch" appear on Joey's chest, a bedsheet has been superimposed over the word "Bitch". However, you can still hear the word being scratched into his chest.
Some television versions enhance the text displayed on the computer monitor when Dr. Neil Gordan is researching the drug Hypnocil. This is due to the fact that the text displayed has faded over the years.
Some gory shots were cut from the U.S. release to earn an "R" rating rather than an "X".
