According to Sestero and Greg Ellery, Wiseau rented a studio at the Birns & Sawyer film lot and bought a "complete Beginning Director package", which included two film and HD cameras. Wiseau was confused about the differences between 35mm film and high-definition video. He wanted to be the first director to film an entire movie simultaneously in two formats. He achieved this by using a custom-built apparatus that housed both cameras side by side and required two crews to operate. Only the 35 mm footage was used in the final edit.
