An additional star-studded lineup of participants has been announced for this year's 24 Hour Musicals, set for June 16 at Classic Stage Company's Lynn F. Angelson Theatre. The 24 Hour Plays presents the annual intensive theatrical endeavor where artists write, rehearse, and perform four new musicals in just 24 hours.

Newly announced are Osh Ashruf, Becky Ann Baker (Assassins), Abigail Breslin (Little Miss Sunshine), Lilli Cooper (POTUS), Rachel Dratch (Saturday Night Live), Andrew Leeds (Bones), Warren Leight (Just in Time), Itamar Moses (Dead Outlaw), christopher oscar peña (A Cautionary Tale), Gabrielle Ruiz (Crazy Ex-Girlfriend), and Meredith Scardino (Girls5Eva). 

They join the previously announced Carolyn Cantor (Sell/Buy/Date), John Carrafa (Urinetown), Morgan Siobhan Green (Hadestown), Jesse Eisenberg (Happy Talk), Alexis Floyd (Grey’s Anatomy), Michael R. Jackson (A Strange Loop), Bebe Neuwirth (Cabaret), Maulik Pancholy (30 Rock), and Peppermint (Head Over Heels). Additional artists will be announced shortly.

The 24 Hour Musicals process begins the night before the performance, when writers, composers, directors, choreographers, actors, musicians, and production staff gather for a short orientation. Four writer and composer teams then craft short musicals overnight, while actors and directors get some rest before receiving their scripts in the early morning. After a flurry of rehearsals, the brand new musicals take the stage for a one-night-only production, complete with an audience and live band.

Tickets start at $99 and are available at 24HourPlays.org. Proceeds support the organization's non-profit activities throughout the year, including educational programming for students of all ages, professional development for emerging artists through The 24 Hour Plays: Nationals, and partner productions all around the world.
