CBS has added to the cast of its much-buzzed about new drama Under the Dome, which is based on the 2009 Stephen King novel of the same name, and follows residents of a small town that is inexplicably and suddenly sealed off from the rest of the world by an invisible force field, as they search for answers as to what the barrier is, where it came from and when/if it will go away.

Joining the series cast is relative newbie, Nicholas Strong, who you might recall starred in the Round 4-winning short film of the Shadow and Act Digital Filmmaker Showcase (Nick Of Time) directed by Eric Haywood.

You'll also find him currently on ABC's drama Nashville.

In Under The Dome, Strong will play a character named Phil, described by THR as "a popular radio DJ and indie rock fan who's a charismatic figure with a dark secret."

He joins Britt Robertson, Natalie Martinez, Alex Koch, Colin Ford and Jolene Purdy.

CBS Television Studios is producing the drama, which was picked up straight to series, in association with Steven Spielberg's Amblin Television.

Niels Arden Oplev (Unforgettable, Sweden's The Girl With the Dragon Tattoo) will direct the first episode.
