EXCLUSIVE: Black List alumni Matt Cook has come on board to adapt Button Man: The Killing Game for DreamWorks. The scribe joined the film last month. Previously, Insomnia scribe Hilary Seitz and Paranoia co-screenwriter Barry Levy had worked on the adaptation of the ultra-violent graphic novel created by John Wagner and Arthur Ranson. Drive director Nicolas Winding Refn is helming Button Man. The story centers on Harry Exton, a hired gun who decides to abandon the death match that gambling millionaires have set up to amuse themselves. In the process of opting out, he finds he might not only have to kill his fellow contestants but also the guys pulling the strings. The film is produced by Roger Kass, Josh Braun, Mark Sourian and Michael De Luca.

Mandeville Films is set to produce Cook’s 2009 Texas-based Black List script By Way Of Helena with Kieran Darcy-Smith directing. Cook is repped by WME and Anonymous Content.
