CBS has tapped Grey’s Anatomy alumna Katherine Heigl to star in its legal drama pilot Doubt, from former Grey’s executive producers Tony Phelan and Joan Rater. The project, produced by CBS TV Studios and Timberman/Beverly Prods, centers on Sadie Ellis (Heigl), a smart, chic, successful defense lawyer at a boutique firm who shockingly gets romantically involved with one of her clients, Billy, who may or may not be guilty of a brutal crime.

The pilot did not make the cut to series in May but the network left the legal drama in contention for a new pilot. The two lead roles of Sadie and Billy were set for recasting, while the rest of the original cast is returning. That includes Laverne Cox, Dule Hill, Dreama Walker, Elliott Gould and Kobi Libii. Also coming back is director Adam Bernstein who helmed the original pilot.

Cox plays Cameron Wirth, a transgender Ivy League-educated attorney. Hill plays Albert Cobb, Sadie’s law partner and close friend with a good sense of humor. Walker plays Tiffany Simon, a smart, hard-working second year associate from Iowa who reports to Cameron. Gould plays Isaiah Roth, the head of the boutique go-to criminal defense firm in New York. Libii plays Nick Brady, a smart, ambitious and enterprising recent law school graduate.

The role of Billy has not been recast yet.

Executive producing the pilot are Tony Phelan & Joan Rater, Carl Beverly & Sarah Timberman and Bernstein.

In her return to series television after her controversial exit from Grey’s Anatomy, Heigl recently headlined NBC drama series State Of Affairs, which opened well, in part due to Heigl’s name recognition, but quickly fizzled and did not go beyond its original order. The Emmy-winning actress (for Grey’s), repped by WME, Nancy Heigl and Silver Lining Entertainment, will next star in the Warner Bros feature Unforgettable, the directorial debut of producer Denise Di Novi.
