After picking up the project nearly a year ago, Lionsgate has now attached The Adjustment Bureau director George Nolfi to helm and oversee a rewrite of the social media thriller XOXO.  The project was initially written by Black Swan scribe Mark Heyman on spec, and was pitched as a modern day Fatal Attraction that explores the dark side of virtual relationships as it follows an up-and-coming executive who blurs the line between his real-life fiancé and his online affair.  The pic will utilize "stylized visual sequences" to portray the online interactions, bringing a whole new meaning to the term "poke."Hit the jump for more on this “Facebook thriller" that has Darren Aronofsky and Michael London (Sideways) onboard as producers.The story of XOXO centers on a rising executive who enjoys a little online flirtation from time-to-time despite the fact that he’s engaged.  He then “meets an alluring woman on Facebook and the two begin a virtual relationship, but the protag soon discovers that his Internet romance is seeping into his actual life in a deadly way.”  Nolfi penned both The Bourne Ultimatum and Ocean’s Twelve before making his directorial debut on last year’s The Adjustment Bureau, which he also wrote.  Variety reports that Nolfi will direct XOXO and oversee a rewrite by Heyman.Though the premise on the surface sounds a tad Cruel Intentions-esque, the involvement of Aronofsky, London, and now Nolfi adds some clout to the project.  Nolfi was on Marvel’s shortlist of directors for the Captain America sequel, but the studio ultimately went with Joe and Anthony Russo for the job.  He recently signed on to rewrite and direct the Cuban Missile Crisis drama One Minute to Midnight, but it’s unclear whether that project or XOXO is next up on his directorial docket.
