Hayley Mills will host a benefit for Only Make Believe on Monday, Nov. 4 at the Westside Theatre.

Featuring a host of talent from the casts of Hairspray, The Producers, Thoroughly Modern Millie, Mamma Mia!, Into the Woods and Oklahoma!, the evening will benefit the charitable organization that brings theatre to hospital-bound children. Among the performers taking part in the 8 PM event are Shoshanna Bean (Hairspray), Brad Oscar (The Producers), Marc Kudisch (Thoroughly Modern Millie), Louise Pitre (Mamma Mia!), Chad Kimball (Into the Woods), Patrick Wilson (Oklahoma!) and Brian d'Arcy James (recently in Sweet Smell of Success) as well as Ann Harada, Anne Runolfsson, Janet Metz, Liz Larsen, Orfeh, Kevin Pariseau and Andrew Lippa.

Only Make Believe was founded in October 1999 at Rusk Institute's Pediatric Unit of the NYU Hospitals Center as a project of the James and Dena Hammerstein Foundation. Since its debut, the project has already provided hundreds of workshops for children in New York City medical facilities.

Only Make Believe will be held at the Westside Theatre, which is located in New York City at 407 W. 43rd Street. For tickets or further information, call (646) 336-1500.
