Walt Disney Pictures has tapped scribe David Benioff to bring his take to the long-gestating action project “Gemini Man.”Benioff — who’ll pocket a fee of $2 million — will be doing a ground-up reworking of the story of an over-the-hill hitman forced to do battle with a younger clone of himself. Pic will be produced by Jerry Bruckheimer, who boarded the project about nine months ago; Bruckheimer toppers Mike Stenson and Chad Oman will exec produce along with Angry Films’ Don Murphy. Jason Reed will act as creative executive for the Mouse. The project was set up in 1997 by Murphy, and was an original pitch from then-tyro Darren Lemke. Over the years, a number of writers have been linked with the project, including “Armageddon” and “Next” scribe Jonathan Hensleigh.
