Steppenwolf Theatre has announced that ensemble member Rondi Reed and frequent guest artist Deanna Dunagan, who both won Tony Awards for their performances in August: Osage County on Broadway last season, will reprise their roles when the play heads to London for an engagement at the National Theatre this fall. Dunagan and Reed won their Tonys for best actress and best featured actress respectively for playing roles they created when the drama–written by ensemble member Tracy Letts, who garnered both a best-play Tony and a Pulitzer Prize for his work–debuted at Steppenwolf last year. The London production will also feature original cast members Amy Morton (who was also Tony-nominated for best actress but lost to Dunagan), Ian Barford, Kimberly Guerrero, Mariann Mayberry, Sally Murphy, Jeff Perry, and Troy West. Also on board for the London engagement are director Anna Shapiro, who won the best director Tony, and the original design team, including Tony winner Todd Rosenthal (sets).
