The Signal is an independent science fiction horror / psychological thriller film written and directed by David Bruckner, Dan Bush, Jacob Gentry and produced by Alexander A. Motlagh"?four filmmakers who have been collaborating since 1999 in Atlanta, Georgia. The movie was completed for the 2007 Sundance Film Festival on a budget of only $50,000 and shot over the course of 13 days.
The Signal is told in three parts, in which all telecommunication devices broadcast only a mysterious "Signal" turning people into psychopaths. The film is broken up into three chapters ("transmissions"), each of which had different directors during shooting. Each part manifests elements of the following genres: splatter film, black comedy, and a post-apocalyptic love story.
