First up, James Gunn's "favorite actor" and brother Sean is joining the cast of The Belko Experiment. You may know him as Kraglin in Guardians of the Galaxy or Toby in Super. He'll play "Marty Espenscheid, a stoner cafeteria worker who has his own ideas about who is behind Belko."
Marty is going to need a best friend and Gunn has chosen standup comedian Steve Agee (The Sarah Silverman Program) to play Chet Valincourt.
The cast also includes John Gallagher, Jr, Tony Goldwyn, Adria Arjona, Melonie Diaz, John C. McGinley, and Owain Yeoman. The film is being directed by Greg McLean from a script written by James Gunn, and is being produced by James Gunn and Peter Safran.
The Belko Experiment will begin filming in Bogota, Colombia in just a few days.
