'Under The Dome' adds to cast

The upcoming Stephen King series "Under The Dome" has added two more cast members, CBS announced today.

Natalie Martinez ("CSI: New York") will step into the role of Deputy Linda, a young, ambitious new deputy who exhibits a strong loyalty to veteran town Sheriff Duke Perkins.

Joining Martinez in the cast will be newcomer Alex Koch. Koch will portray Junior Rennie, son of a Chester's Mill politician and car dealer. The young college student is hopelessly in love with girl next door Angie, a waitress desperate to escape the small town environment of Chester's Mill.

Based on the Stephen King novel, "Under The Dome" centers on the residents of a small community who must deal with postapocalyptic conditions when a mysterious barrier encloses the town, trapping those inside and cutting them off from the support of the outside world.

The best-selling book was given a straight-to-series order, with its 13 episode first season set to debut this summer. The series is produced by CBS Television Studios, partnering with Steven Spielberg's Amblin Television. Brian K. Vaughan, writer of the acclaimed comic-book-that-should-really-be-adapted-to-television "Y: The Last Man", penned the television adaptation of King's novel, and will serve as executive producer along with King, Justin Falvey, Darryl Frank and Stacey Snider. Director Niels Arden Oplev ("Unforgettable", "The Girl With The Dragon Tattoo") is set to direct the first episode.
