 By 2000, Davis had begun writing the screenplay; when the script was finished, however, studios refused to get it made after the Columbine High School massacre happened, causing him to shelve the project and return to making low-budget independent films.During his subsequent years as an independent filmmaker, Davis started putting together an animatic of the script's action scenes using a Wacom tablet and the iMovie app.The animatic, which he made originally as a hobby, became his pitch animation in finding a producer for the project.
