Race, which completes Philadelphia Theatre Company's 2010-2011 season, will run Jan. 21-Feb. 13, 2011, in the Suzanne Roberts Theatre. Mamet's play will conclude its Broadway run Aug. 21.

Broadway producers were coy in their initial descriptions of the latest work from Mamet, the Tony and Pulitzer Prize-winning playwright of Oleanna, Glengarry Glenn Ross and Speed-the-Plow, and kept audiences guessing as to the thrust of the new play.

Here's how PTC describes the play: "Two lawyers, one black and one white, are offered the chance to defend a wealthy white executive charged with committing a provocative crime against a young black woman. When a new legal assistant gets involved, suspicions bubbling beneath the surface explode."

"David Mamet presents a fascinating, funny and theatrical forum for exploring one of our nation’s most taboo subjects," said PTC producing artistic director Sara Garonzik in a statement. "He continues to be one of our bravest and most original writers and we are honored to again be producing his work on our stage as a part of our 35th anniversary season."

PTC's 35th anniversary season also includes the multiple Tony Award winner The 25th Annual Putnam County Spelling Bee, with music and lyrics by William Finn (Nov. 12–Dec. 12), the Philadelphia premiere of Anna Deavere Smith in her one-woman, award-winning show Let Me Down Easy (March 18–April 10, 2011), and the 2009 Pulitzer Prize-winning play Ruined by Lynn Nottage (May 20–June 12, 2011).
