Coming to probably the biggest stint in his screenwriting career so far, "I'm Not There" co-writer Oren Moverman has signed on to work on the script of large-scale drama "Empire", Warner Bros. Pictures' adaptation of Orson Scott Card's novel of the same title published last year.

Set in the near future, the novel finds America in a state of chaos. The assassination of the president and vice president plunges America into civil war, prompting a team of special-forces operatives to embark on a mission to unravel the conspiracy behind and save the country.

Still no word yet on director and star, but it has already been confirmed that Joel Silver is serving as producer via his Silver Pictures shingle. Silver, who last produced thriller horror "The Reaping" also for Warner Bros., recently revived "He-Man and the Masters of the Universe" with Justin Marks penning the screenplay.
