Earlier this month, CBS announced that it was going forward with “Under The Dome,” a Steven Spielberg produced adaptation of the novel with the same name by Stephen King. And with a summer debut looming, casting is picking up speed.

Natalie Martinez and Alex Koch are the two newest additions to the cast of “Under The Dome,” which takes place in Chester’s Mill, a small New England town that finds itself cut off from the world by a mysterious dome.

Martinez will portray a Sheriff’s deputy named Linda, who is described as “young” and “ambitious” as well as “fiercely loyal to Sheriff Duke Perkins.” Martinez has previously had roles in “CSI: New York,” “Sons of Tucson,” “Detroit 1-8-7,” Death Race (pictured above), End of Watch and the upcoming film, Broken City.

Koch will play Junior Rennie, the smart and deeply disturbed son of a local politician who is “desperately in love with local girl Angie, a waitress who’s desperate to get out of Chester’s Mill.”

Colin Ford was previously announced to be playing a teenager named Joe, who finds himself trapped inside the dome and cut off from his family.

“Lost” veteran, Brian K. Vaughan wrote the pilot episode of “Under The Dome” and The Girl With The Dragon Tattoo helmer, Niels Arden Oplev is set to direct the pilot episode as well. The 13 episode first season is slated to premiere this summer on CBS.
