While Machine Gun Preacher may sound like a B-movie straight out of Roger Corman's vault, it's actually aiming to be an action-drama about a biker-turned-Mother Teresa helping children in Uganda and Sudan. Weirder still, it's based on a true story!

Based on Sam Childers' strange journey, Machine Gun Preacher will be coming at you from Lionsgate and director Marc Forster, from a screenplay by Jason Keller (Immortals). Gerard Butler, who has guns of his own, will be portraying Childers, the once-violent gang member who embarks on a spiritual path and becomes a warrior for the desperate and helpless.
