Christine Ebersole

Tony winner Christine Ebersole has joined TBS' Vince Vaughn comedy pilot Sullivan and Son.

Sullivan stars comedian Steve Byrne as Steve Sullivan, an attorney who quits his job to take over his family's legendary bar that serves as the unofficial "town hall" of the working-class Pittsburgh neighborhood. The project chronicles his attempt to find a more rewarding life behind the bar.

The Royal Pains and Retired at 35 actress will play Carol, a lovable drunk at the bar who perpetually overshares details of her wild life and mother to Steve's childhood friend on the half-hour project, The Hollywood Reporter has learned.

Ebersole joins a cast that includes Dan Lauria, Brian Doyle-Murray, Valerie Azlynn, Brooke Lyons, Vivian Bang and Brian Scolaro in the multicamera comedy.

Byrne is producing and penning the project, with Cheers alum Rob Long on board as showrunner; Peter Billingsley (Iron Man) will executive produce alongside Long. Ted Wass is directing the pilot, which began shooting last month in Los Angeles.

The project, which was picked up to pilot in September, hails from Vaughn's Wild West Picture Show Productions and Warner Horizon.

Two-time Tony-winner Ebersole (42nd Street, Grey Gardens) is a former "Weekend Update" host on NBC's Saturday Night Live; her TV credits include Ugly Betty, Valerie's Family and Ryan's Hope. On the feature side, she's appeared in Amadeus andConfessions of a Shopaholic, with The Wedding slated for next year.

She is repped by APA.
