Stumbled upon this blu-ray browsing the used items on amazon. Apparently the production company let the rights for a Doctor Strange movie expire and instead made this.
Wikipedia says that some concept art for the planned Doctor Strange feature that was drawn by Jack Kirby exists.
The He-Man soundtrack is a must have for an old MOTU hound like me, but what i almost like a bit more is the soundtrack for The Brave And The Bold. I like the show and the music apart from the musical shenaningans from the Music Meister epsiode, which of course was fun once or twice, but took away from the excellent score that was already there.
