No functionality of the Medusa car was faked during filming. The real-life car is equipped with two flamethrowers, smoke screen, a bleach drift-kit, adjustable rear suspension, and 3 surveillance cameras; all controlled from the dashboard. It also has a roll cage and stow-able, fold-down back seat.
Evan Glodell and Tyler Dawson, now old friends, originally met in 2003 after Evan saw him in a small play and cast him as the role of Aiden. The early version of the film was to be shot on a camcorder, mostly inside Evan's small apartment. Five years later, after an attempt to make Bellflower and working on many other projects (and at one point becoming roommates), they finally returned to the original purpose of their meeting when the current version of Bellflower went into production in 2008.
