Robert LuPone and Celia Weston have been added to the cast of the Broadway revival of True West, set to open at Circle in the Square Theatre March 2. The veterans join previously announced Philip Seymour Hoffman and Chicago actor John C. Reilly.

Ron Kastner (RJK Productions) is producing the revival of Shepard's 1980 dark comedy, due to start previews Feb. 17 (recently pushed forward from Feb. 15) for what looks to be an open run, according to a spokesperson.

LuPone's credits include A Chorus Line and 1995's Clothes For a Summer Hotel at OB's York Theatre. He also coproduced 1998's Anadarko with Manhattan Class Company, where he serves as co executive director. Weston appeared in the Roundabout's 1996 revival of Summer and Smoke and won an Outer Critics Circle Award for her work in 1997's Tony winner, The Last Night of Ballyhoo.

In True West, Hoffman and Reilly star as Austin and Lee, brothers who end up completely reversing their value systems. Hoffman's recent New York credits include The Skriker, The Author's Voice and Shopping And Fucking. Reilly followed Chicago's Steppenwolf troupe to Broadway in The Grapes of Wrath in 1990. Not only did Reilly and Hoffman appear together in such films as "Hard Eight" and "Boogie Nights," Reilly was instrumental in bringing Hoffman on board for True West.

Matthew Warchus, who directed True West in London in 1994, will helm the staging, which will be the first time the show has made it to Broadway. Its 1980 debut, at the Public Theater, featured Peter Boyle and Tommy Lee Jones. The more famous 1982 staging at the Cherry Lane Theatre featured Chicago actors Gary Sinise and John Malkovich. Their pairing was eventually taped for broadcast on public television. Other plays by Shepard include Simpatico (recently filmed by director Warchus), Cowboys, Seduced, A Lie of the Mind and Curse of the Starving Class. 1978's Buried Child won the Pulitzer Prize and received a recent Broadway revival directed by Sinise.
