The Sound Inside star Mary-Louise Parker told the The Today Show that she was out walking her dog when she finally committed to doing Adam Rapp’s play. Although initially hesitant to star because she thought someone else could do it better, Williamstown Theatre Festival runner Mandy Greenfield encouraged her to take on the role.

The Tony winner for Proof and Emmy winner for Angels in America is now on Broadway in the two-hander, opposite Will Hochman at Studio 54. “I just found the writing so compelling,” said Parker of Rapp’s script. “He’s so gifted. His prose is just so beautiful.”
