The theatrical trailer for director Marc Forster’s (Monster’s Ball and Quantum of Solace) Machine Gun Preacher has hit the interwebs. Starring Gerard Butler, Michelle Monaghan, and Michael Shannon, the film tells the true story of Sam Childers (Butler), a former drug-dealer who goes on to save the lives of hundreds of kidnapped and orphaned kids in Sudan. While I can’t claim to be Butler’s biggest fan, I have to say that he looks to be in his element in Preacher as a hardened guy who wants to do the right thing the only way he knows how: through violence. Add that in with the fact that I’ve enjoyed much of Forster’s previous work, and Machine Gun Preacher is a film I’m looking forward to watching.Check out the trailer after the jump. Machine Gun Preacher will premiere at the Toronto International Film Festival next month and opens theatrically on September 23rd.
