CAA is shopping a package around town for an untitled sci-fi feature from scribe Nic Kelman (“Genneris”), with “Clash of the Titans” helmer Louis Leterrier attached to direct and Lorenzo di Bonaventura on board to produce.Paramount has first dibs on the project thanks to its first-look deal with Di Bonaventura Pictures, which produced the studio’s boffo “Transformers” trilogy. Paramount hasn’t made an offer yet and other studios remain in the mix for the package, which has several attractive elements, including Leterrier’s interest. While plot details remain under wraps, sources describe Kelman’s pitch as a low-budget, contained sci-fi pic. Di Bonaventura is a trusted producer on the Melrose lot, as his company is behind the studio’s “G.I. Joe” franchise as well as its upcoming Jack Ryan reboot, which has Kenneth Branagh directing and starring opposite Chris Pine. Leterrier is the director of “The Incredible Hulk” and “Clash of the Titans” whose latest film, the star-studded magician heist pic “Now You See Me,” has been garnering early buzz for Summit. Helmer is also developing the sci-fi pic “G” for Universal. Kelman is best known in Hollywood circles for writing the high-concept sci-fi spec script “Genneris,” which DreamWorks acquired in March 2011. Seven months later, Mandalay Pictures tapped the scribe to adapt Liquid Comics’ 2006 graphic novel “Ramayan 3392 AD.” Kelman also wrote the best-selling novel “girls,” which Little, Brown and Co. published in 2003. CAA reps Kelman and Leterrier, who’s also repped by Management 360. Kelman is also repped by 3 Arts Entertainment and attorney Michael Gendler of Gendler & Kelly.
