Columbia has picked up the spec script "Supermax" from actors-turned-writers Mitch Rouse and Christopher Nelson. Todd Garner will produce via his Broken Road Productions banner.
The spec is an action horror tale set in a maximum-security prison for the supernatural. The story centers on a skilled prison guard who is re-assigned to Supermax. After a riot erupts, he must join forces with one of the prison's monstrous inmates in order to survive and fight his way out.
Sony's Doug Belgrad and Devon Franklin will oversee for the studio. Sean Robbins is executive producing for Broken Road.
