I watched this movie 15 or more years ago.  It was in color, and in English.  The one scene that sticks in my head is when the male and female character are coming down the stairs.  They did a whole choreographed series of maneuvers, stepping up and back, left and right, stepping in different directions, sometimes side-by-side, sometimes not.  I think (not very sure) that the film may have had a single-word title, and it might have been a made-up/nonsense/fantastical word.  It’s definitely a B-movie (maybe C or D?) like something Troma might have done, but it wasn’t a Troma flick.  It was a weird movie, not sure what actual genre it belonged in.  Sorry that’s all I can remember, but I have been wracking my brain for a couple of years now, and I just found this site.
