Brett Cullen & Max Ehrich Join 'Under the Dome'; Stephen King to Make a Cameo

Lost and Devious Maids actor Brett Cullen has joined the cast of CBS summer drama Under the Dome. He will appear in a multi-episode arc as Don Barbara, the father of Mike Vogel's Barbie.

SPOILER ALERT...

The smooth, charming and powerful patriarch of the Barbara clan, Don runs a multi-national corporation. Barbie is shocked to find himself face-to-face with his father in an unforgettable turn of events.

The second season will move past Stephen King's book, storyline-wise but King is giving it his blessing by writing the first episode and making a cameo.

This season will include a digital-only character who is able to communicate with characters trapped in the dome. It is part of an effort to reach out to the show's young audience and embrace transmedia.

Max Ehrich (Fenmore on The Young and the Restless) has also joined the Under the Dome cast. He will play Hunter, who will first appear "digitally" in the third episode says executive producer Neal Bauer.
