I first saw The Room about five years ago and thought it was the greatest bad movie of all time. I love so-bad-it's-good movies and I've seen a lot of them.
When I heard that James Franco was making a movie about The Room, I re-watched it. I still have yet to see The Disaster Artist but based on yours and others' reviews, I look forward to watching it.
Tommy Wiseau acts like Jeff Bridges' character in Starman which makes sense because nobody knows where Wiseau comes from either. Some have said it's Poland but don't rule out outer space.
