Tommy Wiseau has long been fascinated by vampires, which isn't surprising because he basically is one. In The Disaster Artist, Sestero wrote about how he had to talk Tommy out of including an extension of the Chris R. fight scene where Johnny's Benz would ascend from the rooftop and fly into the night sky, exposing that Johnny is actually a vampire. How Tommy's mind envisioned this fitting into the plot, we may never know.
