Parenthood is based on the 1989 film that has the same name. The show is about the reunion of a multigenerational family in California. The series will be on hiatus until early 2010, reports the New York Times.

In the meantime, the Hollywood Reporter is saying that the show Mercy will take its place. The medical drama's cast has been called in early to get the first episode ready for September.
