Former G.D.H. International Vice-President of Creative Affairs Eric Calderon (Afro Samurai, Linkin Park's "Breaking the Habit" music video) posted on his personal website a pilot video for The Five Killers, a 12-episode animated television series under development at the animation studio Gonzo. Calderon's story features five killers being hunted down by an assassin and the tagline, "3 Die. 2 Survive. 1 Lives… Forever."
The project's staffers includes pilot director Tomohiro Hirata (Trinity Blood), writers George Krstic (Megas XLR co-creator, Star Wars Clone Wars writer) and Mark Waid (Kingdom Come, JLA, Voltron comics), and designer Shigeki Maeshima (Robot). Calderon made one of the first public mentions of this project in a tongue-in-cheek question to his former boss, Gonzo CEO Shin Ishikawa, during Anime Expo 2007's keynote panels.
