LOS ANGELES -- When last we saw Calista Flockhart on television, she was dancing into the sunset as Ally McBeal. Rachel Griffiths, meanwhile, was dying under a load of old-age makeup on "Six Feet Under."

Both actresses are now plotting a return to the small screen in an ABC pilot.

The two multiple Emmy nominees -- Flockhart earned three nods for "Ally McBeal" and Griffiths two for "Six Feet Under" -- have signed on to the family drama "Brothers & Sisters," the showbiz trade papers report. The show revolves around a group of adult siblings who run their family's business following the death of their father.

Griffiths and Flockhart join a cast that also includes "Alias" regulars Balthazar Getty and Ron Rifkin and "Reunion's" Dave Annable. Writer Jon Robin Baitz ("The West Wing") and Ken Olin ("Alias") are executive producing the Touchstone TV project.

Flockhart has kept a fairly low profile since "Ally McBeal" ended its tenure on FOX in 2002. Her only credits since then include the 2004 film "The Last Shot" and a movie called "Fragile" that's set for release in the U.S. later this year.

Griffiths comes to "Brothers & Sisters" following the end of "Six Feet Under" last year. Her other credits include an Oscar-nominated performance in "Hilary and Jackie," along with "The Rookie" and "Muriel's Wedding."
