Does anyone know the name of the movie that came out in the '80s or so that was about a character who was pretty much like Dr. Strange but was called something else. The title of the movie was the character's name, I think, like Dr. Magus or something? He lived in an apartment, but when you went in the door, the place was impossibly huge. That's all I remember, but I remember liking it and would like to see it again. I rented a VHS tape a few time, but can't find the name anymore.

Thanks.
