Dr. Who?
Little is known about Dr. Z except he's been around the block for a long time, has his own production company and seems to admire Bruce Lee. He has made a handful of movies that are shown for special screenings at theaters. He used to sell his films on VHS and DVD on his own website (probably still does). Some can be streamed through VIMEO (I think).
I have never seen any of his stuff and I assume most people haven't either. The availability is limited, and his movies don't even have voting counts at IMDb.
It seems that some of his films are older than the newer dates added. No reviews exist (I couldn't find any), It's like he is making these movies for his own pleasure.
If you ever come across a Dr. Z feature, please share your thoughts
