The reading, which will be directed by Leigh Silverman, will benefit TDF Open Doors (tdf.org/opendoors), a mentoring program co-founded by Ms. Wasserstein and Roy Harris that "matches dozens of distinguished theatre and dance professionals with small groups of high school students with no prior exposure to theatre."

The reading will star Celia Keenan-Bolger as Kate Quin, Graynor as Samantha Stewart, Merritt Wever as Holly Caplan, Lisa Joyce as Muffet DiNicola, Aya Cash as Rita Altabel, Lisa Kron as Mrs. Plumm, Jenni Barber as Susie Friend, Tracee Chimo as Carter and Cristin Milioti as Leilah with Byron Jennings as The Male Voice and Melissa Ross as Narrator/ Stage Directions.

Graynor replaces the previously announced Laura Benanti, withdrawed from the event due to a scheduling conflict.

Set amidst the second-wave feminist movement of the 1970s, Uncommon Women and Others, according to press notes, "follows the lives, loves, and losses of a close-knit circle of friends at Mount Holyoke College (itself Wasserstein’s own alma matter.) As the women reunite six years after graduation, the story flashes back to the seminal moments in their lives as classmates to examine what inspired them, what affected them, and ultimately what shaped them."

The evening is produced by The Indigo Theatre Project (Nick Gereffi and Rachel Sussman, co-founding artistic directors), a theatre company that strives "to unite passion with purpose by producing high-profile readings of notable plays to benefit charities aligned with the work being read." Theresa Lang Theatre at Marymount Manhattan College is located at 221 East 71st Street.
