Billy Crudup, Brooke Shields, Mos Def, John C. Reilly, Rosie Perez, Sam Rockwell, Fisher Stevens, Julianna Margulies, Marisa Tomei, Matthew Lillard and Katherine Kellner are scheduled to appear in plays written by Jeff Whitty (Avenue Q), Julia Jordan (Boy, St. Scarlet) and others. (The lineup of artists is subject to change). Details Magazine and Bloomingdale's once again present The 24 Hour Company and Planet Impact special event with proceeds going to support Working Playground.

The full one-day process of The 24-Hour Plays begins at 10 PM the night prior to performance. Typically, a group of theatre artists (playwrights, directors, actors and designers) meet and are briefed and photographed. The writers are then left to their own wits to produce a ten-minute play. The following morning at 7 AM, the directors give the scripts a once-over, divvy them up and cast them. Actors make their entrance at 8 AM and rehearse through the day. The technical rehearsals run from 5 PM to 7:30 PM. Doors open at 7:45 PM and curtain rises at 8 PM and voila: six shows, all in a day's work.

Those involved in this production join a long line of artists who have participated in over 300 new short plays that The 24 Hour Plays has produced since its inception in 1995.

Tickets to the event at the American Airlines Theater, 227 W. 42nd St., are on sale by calling (212) 868-4444. For more information on the benefit and the company, visit www.24hourplays.com.
