On the last day of shooting, the team arrived early to the final location at Elysian Park overlooking downtown LA, to learn that the city had double booked the location. A city wide orchestra event was taking place, and there were 10 saxophone players standing in the center of the location. With daylight running out, the Mad Genius crew had to work with the saxophone players, stopping every 15 minutes to let them serenade a new group of concert goers.
The director Royce Gorsuch postponed his commercial directing career and moved into the hacker warehouse location of the movie to make Mad Genius. He wanted to live along side real life hackers in the underground warehouse world of the film. In the background of the "doorway kick" scene was his bedroom.
