Rosemarie DeWitt Drops Out of THE NEWSROOM

"As the production schedule for season two of The Newsroom has shifted, Rosemarie DeWitt has encountered scheduling conflicts and will no longer be able to continue in her role," HBO said in a statement released today.

It was originally announced in November that DeWitt had signed on to the HBO series alongside UNITED STATES OF TARA co-star Patton Oswalt.

According to Deadline, the actress was to play Rebecca Halliday, "a litigator who's been hired to defend the fictional Atlantis Cable News channel, where the show is set, in a multimillion-dollar wrongful-termination suit."

DeWitt had reportedly already filmed scenes for the show, but as the writers altered her storyline, reshoots were ordered - and DeWitt was unavailable. As a guest star, she was let out of her contract, and the role is now being recast.

DeWitt's latest film, TOUCHY FEELY, is premiering at Sundance this weekend, where she's doing promotional interviews.

Created by Aaron Sorkin (Oscar(R) winner for writing "The Social Network," executive producer and writer of the multiple Emmy(R) winner "The West Wing"), the newHBO drama series follows a news team on its quixotic mission to reclaim the legacy of Murrow and Cronkite in The Face of a fickle audience, corporate mandates and tangled personal relationships.

The series is executive produced by Sorkin, Scott Rudin (the Oscar(R) winner "No Country for Old Men") and Alan Poul (HBO's multiple Emmy(R) winner "Six Feet Under"). Jeff Daniels (Golden Globe nominee for "The Squid and the Whale," "Something Wild" and "The Purple Rose of Cairo") stars as Will McAvoy andEmily Mortimer ("Hugo," "Shutter Island") stars as MacKenzie McHale.
