New poster for Gerard Butlers Machine Gun Preacher

The first poster for the soon-to-be-released Machine Gun Preacher has been unveiled.

The image shows Gerard Butler against a city slum backdrop, holding an AK-47 whilst standing protectively in front of a Sudanese child.

Some questionable Photoshopping makes it looks like it could be a promo for a comedy film-within-a-film vanity project, but, remarkably, this is based on a true story.

The film chronicles the life story of biker Sam Childers, a former drug dealer who found God and became the hero of hundreds of Sudanese children who were forced to become soldiers.

Butler stars as Childers, with Michelle Monaghan supporting. Check out the poster below:

Machine Gun Preacher is set for a UK release of 18 November 2011.
