Porgy and Bess also stars Tony nominee Norm Lewis (Les Misérables, Sondheim on Sondheim) as Porgy and three-time Tony nominee David Alan Grier (Race, "In Living Color") as Sporting Life. The cast also includes Tony nominee Phillip Boykin as Crown, Nikki Renée Daniels as Clara, Joshua Henry as Jake, Christopher Innvar as Detective, Bryonha Marie Parham as Serena and NaTasha Yvette Williams as Mariah, as well as Sumayya Ali, Allison Blackwell, Roosevelt André Credit, Trevon Davis, Joseph Dellger, Wilkie Ferguson III, Carmen Ruby Floyd, Gavin Gregory, Heather Hill, David Hughey, Andrea Jones-Sojola, Alicia Hall Moran, Cedric Neal, Phumzile Sojola, Nathaniel Stampley, Julius Thomas III, J.D.

The creative team includes Diane Paulus (Hair), Pulitzer Prize-winning playwright Suzan-Lori Parks (Topdog/Underdog), and two-time Obie Award-winning composer Diedre L. Murray (Running Man). They reinvent the onetime "folk opera" from 1935 as a musical that still captures the heart, soul, music and juicy story first created by DuBose Heyward, Dorothy Heyward, George Gershwin and Ira Gershwin.
