Amidst furiously prepping his Marvel sequel Guardians of the Galaxy 2, James Gunn has written and will produce an indie horror movie directed by Greg Mclean. The movie is titled The Belko Experiment, and follows a group of 83 American expatriates who work in a building in Sao Paulo, Brazil, and find themselves trapped in their workplace; a voice emits over the speaker system, forcing them through a series of murderous moral decisions. James Gunn has previously announced John Gallagher Jr., Tony Goldwyn, Melonie Diaz and Michael Rooker for the main cast. He has now issued another statement, bringing aboard three more actors. Here is his press release:

More employees of Belko are here. I'm realizing I don't have long before I leave for Columbia, so I have to get more of our cast out there. David Dastmalchian is a guy I've known for a while. We met while both doing cameos in a friends' film, immediately hit it off, and have wanted to work together ever since. He most recently has joined the Marvel family in Ant Man. And because he's bi-comic-book curious, he was also the Joker's henchman in the Dark Knight, joining a very narrow league of actors in both Marvel and DC films. You may recognize him from his awesome role in Prisoners or his great new film Animals. In Belko, he's Alonso "Lonny" Crane, who works for Michael Rooker's character in maintenance. He's a little slow. (Not David, Lonny).

Gail Bean is a woman I just met, but she blew me away in her audition. And meeting her briefly at the table read, I liked her even more. She's a relative newcomer, but she's receiving absolute raves for her role in the film Unexpected, which played at Sundance. She's playing Leota Hynek, who takes the new girl Dany (played by Melonie Diaz) under her wing.

And finally, there's another familiar face for people who know my films. He took the world by storm as Murray Martini in my first ever film Tromeo and Juliet, was the most dickish line-butter ever who more than got what was coming to him in SUPER, and, of course, he played my roommate/life partner/best pal "Val" in Humanzee -Valentine Miele. Someone asked me recently who do you think is the most underrated actor around, and I said Val. He's a truly talented, charismatic guy. He'll be playing Ross Reynolds, a family man and Dutch-speaking sales rep for Belko who doesn't deal well with being forced to kill his fellow employees or die himself. But, then again, who would? I've included a photo of Val dancing with girls in bikinis in Humanzee just 'cuz.

David, Gail, and Val join John Gallagher Jr.,Tony Goldwyn,Adria Arjona, Michael Rooker, Melonie Diaz,John C. McGinley, Sean Gunn, Owain Yeoman, and Steve Agee as their fellow employees. The movie is directed by Greg McLean from my script, and is being produced by myself and Peter Safran. We start shooting in Bogota, Colombia IN JUST A FEW DAYS. I'll name even more employees on Monday.

What do you think of The Belko Experiment cast so far? Are you excited for this James Gunn written and produced exorcise in terror? Or do you think he should just stick to making sure Guardians of the Galaxy 2 is the best it can be?
