EXCLUSIVE: Graham King, who established himself as a producer by doing repeat business with talent like  Leonardo DiCaprio, Johnny Depp, Martin Scorsese and William Monahan, is fast developing that kind of relationship with Angelina Jolie.

I’m told GK Films is developing a feature adaptation of the 2009 British miniseries Unforgiven, and Christopher McQuarrie writing a script that’s being tailored for Jolie to play the lead role. Jolie, who next stars with Depp in the GK-financed Florian Henckel von Donnersmarck-directed thriller The Tourist (Columbia Pictures releases the film December 10), separately announced this week she’ll make her directing debut and produce with GK’s King and Tim Headington a Bosnian love story she has written.

McQuarrie, who just scripted X-Men Origins: Wolverine 2, was one of the writers on The Tourist. Unforgiven is about a woman’s attempt to rejoin society after she serves a 15-year prison stretch for the murder of two policemen. The tragedy happened after the policemen came to evict her family from their farmhouse. Her hope is to live quietly and reunite with her troubled younger sister, but the paroled woman is targeted for a revenge campaign by two sons of one of her victims. Suranne Jones played the lead in the mini, which was written by Sally Wainwright and directed by David Evans.

Jolie doesn’t commit to projects until scripts are completed, but I’m told this one is on a fast track. Jolie solidified her starpower this summer with the action-thriller Salt, which has grossed north of $217 million worldwide. Jolie’s repped by Media Talent Group’s Geyer Kosinski.

GK Films has been building momentum in a summer that saw Peter Schlessel leave his post as Sony Pictures president of worldwide affairs to run the company, and former Picturehouse and Apparition head Bob Berney has been rumored to be in line to start a specialty film distribution arm financed by King and Headington. GK has just begun shooting the 3D Martin Scorsese-directed adaptation of Hugo Cabret, and next opens the Ben Affleck-directed crime drama The Town on September 17 through Warner Bros.
