Sally Field has signed on to star in the TV drama, Brothers & Sisters for ABC.

Variety reports Sally will play the mom on the show replacing Betty Buckley, who played the part in the pilot. And also joining the cast of Brothers & Sisters is Matthew Rhys, taking on the role handled by Jonathan LaPaglia in the pilot.

The family drama, which already stars Calista Flockhart, Rachel Griffiths, Ron Rifkin and Patricia Wettig, revolves around five California-based siblings bound together by familial and financial ties.

Brothers & Sisters is taking over the 10pm Sunday night spot on ABC starting in the fall. That time was held by Grey's Anatomy for the past two seasons.
