Sean Penn is in negotiations to star in the potential franchise-launching action noir "Prone Gunman" at Silver Pictures and StudioCanal.
Based on a Jean-Patrick Manchette novel, the story centers on an international operative named Martin Terrier (Penn) who is betrayed by the organization he works for.
He then goes on the run in a relentless game of cat-and-mouse across Europe. The author's work has been described as "existentialist and involving explorations of politics as well as the human condition."
Peter Travis is adapting the script while Joel Silver and Andrew Rona will produce.
