Under the Dome already has a summer premiere date, so filming will begin shortly, and we have details on two more actors who have joined the project. Jolene Purdy (Glee) and Nicholas Strong are the latest additions to the cast, according to Deadline. Jolene is said to play the role of Dodee, "a brilliant, eccentric engineer at the local radio station who will draw on her unique skills in an effort to make contact with the world outside the dome."

Nicholas Strong (Nashville) has been cast as Phil, "a popular radio DJ and indie rock fanatic, a charismatic figure with a dark secret." For those that missed our previous casting reports, here's everyone else that has been announced so far:

Britt Robertson: Playing Angie, a waitress and aspiring nurse who has always dreamed of escaping Chester’s Mill.

Alex Koch: Cast as Junior Rennie, a character that is in love with Angie. He’s described as “son of the local politician and car dealer, who is a smart, secretly deeply disturbed college freshman desperately in love with local girl Angie.”

Natalie Martinez: Playing Linda, an “…ambitious deputy, fiercely loyal to Sheriff Duke Perkins, who runs a tight ship in the town of Chester’s Mill.”

Colin Ford: Cast as Joe, a “teenager living in Chester’s Mill, a very smart kid who’s understandably freaked out when he discovers that the mysterious barrier covers the whole town — and both his parents are outside of it.”

CBS recently announced that it would be moving forward on a 13-episode first season of Under the Dome, with the first episode airing on June 24th. Niels Arden Oplev (The Girl with the Dragon Tattoo) will be directing the first episode and the story has been adapted by Brian K. Vaughan. For those that haven’t read the 1000+ page novel, Under the Dome was released in 2009 and involves a Maine town that has been cut off from the world by an invisible dome:

“Just down Route 119 in Chester’s Mill, Maine, all hell is about to break loose… On an entirely normal, beautiful fall day, a small town is suddenly and inexplicably sealed off from the rest of the world by an invisible force field. Planes crash into it and rain down flaming wreckage. A gardener’s hand is severed as the dome descends. Cars explode on impact. Families are separated, and panic mounts. No one can fathom what the barrier is, where it came from, and when — or if — it will go away. Now a few intrepid citizens, led by an Iraq vet turned short-order cook, face down a ruthless politician dead set on seizing the reins of power under the dome. But their main adversary is the dome itself. Because time isn’t just running short. It’s running out.”
