The one-day process of The 24 Hour Plays, according to press notes, "begins at 9 PM the night prior to the performance. The group of theatre, film and television artists, which includes playwrights, directors, actors and designers, meet and are briefed on the upcoming 24 hours. The writers are then left to create a ten-minute play overnight. In the morning, the directors read the scripts and then the actors are called for 8 AM. Everyone rehearses throughout the day. Doors open at 7:45 PM, and curtain rises at 8 PM and there it is: six shows, all in a day's work."

The evening is produced by Kelcie Beene and Carly Hugo on behalf of At Play.
