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), is in theaters March 17. Our very own Joe Lipsett reviewed The Belko Experiment out of TIFF calling it “a cocktail of murder and laughs.”

If you thought the film was inspired by Battle Royale before, just wait until you see this red band clip in which a handful of “employees” lose their heads…

The cast is massive, including 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.

Here’s the official synopsis:

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.
