Signature Theatre (James Houghton, Founding Artistic Director; Erika Mallin, Executive Director) welcomes Claire van der Boom (HBO’s “The Pacific” & CBS’ “Hawaii Five-0”) to the cast of Sam Shepard’s HEARTLESS, directed by Daniel Aukin. Claire van der Boom will play the role of ‘Sally’, replacing Julianne Nicholson whose prior commitments prevent her from performing during the two week extension through Sunday, September 30. HEARTLESS is now playing in The Irene Diamond Stage at The Pershing Square Signature Center (480 West 42^nd Street between 9^th and 10^th Avenues). Tickets during the extension weeks are $75 each.

The cast currently includes Jenny Bacon (In the Wake), Gary Cole (Office Space, “The West Wing”), Betty Gilpin (We Live Here), Julianne Nicholson (“Boardwalk Empire”, This) and Lois Smith (The Illusion, The Trip to Bountiful).

Sally lives with her mysterious family in a cavernous home overlooking Los Angeles. When a visitor arrives, Sally’s dark secrets – and the secrets of those around her – threaten to come into the light. A world premiere from the Pulitzer Prize-winning Sam Shepard, Signature’s 1996-97 Playwright-in-Residence.
