The first major acquisition has been made out of the ongoing Toronto International Film Festival as Orion and BH Tilt nabbed Greg McLean’s The Belko Experiment, written by Guardians of the Galaxy director James Gunn (also writer of Dawn of the Dead and director of SLiTHER).

The film, which just premiered at the film festival, will release in theaters on March 17, 2017.

Just how massive is the cast? It includes Tony Goldwyn, Adria Arjona (“True Detective”), John Gallagher Jr. (10 Cloverfield Lane), John C. McGinley (“Scrubs”), Sean Gunn (Super), David Dalmastian, Michael Rooker (Henry, Slither, “The Walking Dead”), Steven Blakeheart, Owain Yeoman, Rusty Schwimmer, Melonie Diaz, Josh Brener, David Del Rio, Abraham Benrubi, Gail Bean, Joe Fria, Ben Davis, James Earl, Brent Sexton, Mikaela Hoover, Valentine Miele.

Back in May, McLean told us that Belko is “insanely violent and totally crazy…and total genius because of it.”

James wrote this amazing script full of heart, hilarious dark humour and amazing characters all wrapped around this wild concept (I won’t give away) so I cannot wait till it comes out and people see the movie.

“Belko revolves around the American Belco company in South America which is mysteriously sealed off at the beginning of a work day,” Gunn explained when announced, “and its employees are ordered to kill each other or be killed themselves. This starts an escalation of violence, where we discover the true nature of each and every Belco employee.”

On what appears to be a normal day at Belko Industries, Belko employees are horrified when they find out that they’ve become guinea pigs in a company-wide experiment which will lead them to either kill their fellow employees or be murdered themselves. The experiment is masterminded by a mysterious voice which is controlling the loud speaker and instructing the employees to slaughter each other by any means necessary.

McLean also directed The Darkness, Wolf Creek and Rogue.
