My theory on this guy.
I am convinced that Tommy Wiseau comes from Eastern European criminal underground, probably prostitution, sex trade, and/or narcotics. He probably talked with his criminal buddies for years about how he wanted to make movies, and he was going to be a big star in Hollywood, and those retards probably agreed. Then, he got his $6 million, and emerged from his criminal underground and tried to be "normal" like us.... this is the result. I am convinced that this is most likely scenario.
It explains why he doesn't talk about his past, and why he hides and lies about where he comes from. He obviously looks eastern european, which is a hot bed for this type of criminal activity since the fall of Soviet Russia.
This next part, is just my instincts... but looking at Tommy's face and eyes... you can tell this guy has been involved with some rough stuff in his life, probably even prison. And with his fabio wannabe persona....
This is what screams out to me when I see this man.
