Risky Biz Blog has learned that CBS Films is developing a feature remake of the long-running TV show Gunsmoke and has signed on National Treasure: Book of Secrets's Gregory Poirier to write the screenplay.

The action-adventure will re-imagine Marshal Matt Dillon, the hero of the classic Western, for modern audiences. The story will be set in the same American West as the original but will feature a contemporary look and modern action twists.

Poirier is close to completing a first draft of the script.
