Peter Krause, Maura Tierney wedded to NBC's 'Parenthood'
"Parenthood" is based on Ron Howard's 1989 film, which previously spawned a short-lived TV series of its own.
< p>The series focuses on the Bravermans (they were the Buckmans in the movie), a group of adult siblings.
The trade says that Krause ("Dirty Sexy Money") will Adam, a seemingly mature married father with a good-girl daughter (Ramos ["American Dreams")), but apparently he has a manic streak running underneath his placid exterior.
Tierney ("NewsRadio") would play single-mom Sarah Braverman, with Whitman ("Arrested Development") as her rebellious daughter.
The Krause and Tierney roles are extensions of the parts played by Steve Martin and Dianne Wiest in the original film.
Shepard ("Zathura") would play the youngest Braverman sibling, while Nelson would play the family patriarch.
Jason Katims ("Friday Night Lights") is developing the pilot for NBC. Howard will executive produce along with Brian Grazer for Imagine TV.
