Maura Tierney drops out of 'Parenthood'

Actress has scheduling conflicts with cancer treatments

Maura Tierney has pulled out of NBC's upcoming drama series "Parenthood" because its production schedule would interfere with her breast cancer treatments.

NBC has begun the process of recasting her role in the project based on the 1989 movie that's written and executive produced by Jason Katims.

"Ms. Tierney and her doctors remain confident that the outcome of her treatments will be positive," Tierney's spokeswoman said Thursday. "She is deeply disappointed that she will not be able to rejoin such a highly respected, talented, fun and funny group of actors and wishes to thank Jason Katims and NBC for their patience and support."

"Parenthood," in which Tierney was to play one of the central characters alongside Peter Krause, Erika Christensen, Dax Shepard, Bonnie Bedelia and Craig T. Nelson, originally was slated to premiere this month but was pushed to midseason in July when, shortly before the series was to enter production, Tierney's doctors discovered a tumor in her breast.

At the time, the production start date was postponed until November to give Tierney time to undergo the necessary medical procedures.

It now appears Tierney's treatment will take longer, so NBC will recast the role in order to make the midseason launch date.

Tierney had garnered strong notices for her performance in the pilot for "Parenthood," where she played a contemporary version of the character portrayed by Dianne Wiest in the movie.

"While we are saddened that Maura Tierney won't be able to continue in her current role in 'Parenthood,' our main concern is for her quick and full recovery," an NBC spokesman said. "Our thoughts and best wishes are with her."

"Parenthood," from UMS, is exec produced by Katims, Ron Howard and Brian Grazer.
