S. Craig Zahler, the writer-director behind the excellent ‘Bone Tomahawk,’ is set to direct Vince Vaughn in the action thriller ‘Brawl In Cell 99,’ says THR. Penned by Zahler, the plot centres on “a former boxer (Vaughn) whose life is crumbling: He loses his job as an auto mechanic and his troubled marriage is about to expire. At this crossroads in his life, he feels that he has no better option than to work for an old buddy as a drug courier. This vocation improves his situation until the day he finds himself in a gunfight between a group of police officers and his own ruthless allies. When the smoke clears, the man finds himself in prison in a no-win situation as his enemies force him to commit acts of violence that turn the place into a savage battleground.” Filming kicks off at the end of summer, with Dallas Sonnier and Jack Heller of Caliber Media producing. XYZ Films is executive producing.
