'Iron' scribes in 'Sigma' fraternity


"Iron Man" co-writers Art Marcum and Matt Holloway have signed on to write the big-screen adaptation of Robert Ludlum's "The Sigma Protocol" for Universal. Paul Sandberg is producing along with Strike Entertainment's Marc Abraham and Eric Newman.

"Sigma" centers on an American economist who becomes the target of professional assassins. When a U.S. intelligence agent investigating his case finds herself discredited, the two end up on the run and uncover a multinational conspiracy manipulating the global economy and world events. The book was one of the last written by Ludlum, who is the creator of the studio's ultra-successful "Bourne" franchise. (Sandberg was a producer on that series, along with Frank Marshall.)

The project was set up at the studio several years ago and at one point had Jonathan Jakubowicz ("Secuestro Express") on board to write and direct.

Scott Bernstein and David Ortiz are overseeing for the studio.

"Sigma" is a continuation of the roll Marcum and Holloway have been on since "Iron Man's" success. The two are penning the "Highlander" remake for Summit and recently penned the original script "Convoy." They are represented by ICM. (partialdiff)
