The limited engagement of British playwright Jez Butterworth's three-hour play, extended once, ends Aug. 21 as scheduled at the Music Box Theatre (239 West 45th Street), prior to the production returning to London's West End, where it will begin performances on Oct. 8 at the Apollo Theatre.

Tony winner Gallagher (Spring Awakening) exited the play on July 17. Sullivan makes his Broadway debut in the dark comedy about a patch of England dominated by Johnny "Rooster" Byron (Tony winner Mark Rylance), a crude, drug-dealing ex-daredevil who knows his way around a tall tale.

Sullivan's credits include New York premieres of Dog Sees God (Soho Playhouse), Durango (Public), Orestes: A Tragic Romp (Folger/Two River), plus regional productions of The History Boys (Helen Hayes nomination) and Rock 'n' Roll (Studio Theatre), among others.

Jerusalem star Rylance won his second Tony Award for his critically acclaimed performance as "Rooster" Byron. He also won the New York Drama Critics Circle, Drama League and Outer Critics Circle Awards for his performance.

Butterworth won the New York Drama Critics Circle Award for Best Foreign Play.

The production also stars Mackenzie Crook as Ginger, Max Baker as Wesley, Alan David as The Professor, Aimeé-Ffion Edwards as Phaedra, Geraldine Hughes as Dawn, Danny Kirrane as Davey, Charlotte Mills as Tanya, Sarah Moyle as Ms. Fawcett, Molly Ranson as Pea, Harvey Robinson as Mr. Parsons, Barry Sloane as Troy Whitworth, and Aiden Eyrick and Mark Page alternating in the role of Marky.
