What is Tommy Wiseau?

Possibility 1: He's an immortal like in Highlander. This would explain why no birth records exist for him- he was born centuries ago. It explains his accent- he was born in a country that no longer exists, and has spent the years wandering the Earth, meaning he has picked up speaking traits from thousands of cultures and people throughout history. It explains why The Room is the way it is, Tommy was using ancient storytelling techniques favoured by his lost civilisation.
