So there was this movie that was either from the early 90's, or from the 80's that was something about a guy whose girlfriend gets trapped in another dimension or something by some evil character guy. Now the good guy of the story goes through all kinds of alternate dimensions looking for his woman. In the end he meets up with the bad guy of the story and they fight. Real specific, I know. But I think I do vaguely remember a point where the good guy and the bad guy turned into blue and red dragons respectively, and fought it out. Of course the dragons looked terrible (If I recall, they were just sort of laser/lightning outlines) as did most of the rest of the movie. But I'd like to get the title of this film again, if anyone can remember it. Any help would be appreciated.
