The marathon process for The 24 Hour Plays on Broadway begins at 10 p.m. the night before the performance. The writers, directors, actors and production staff - many of whom have never worked with or met each other before - gather for an orientation where they are asked to share one costume piece, one prop, a special skill, and to reveal something that they have always wanted to do on stage. Using these items as inspiration, the writers spend the night developing 10-minute plays. At 9 a.m. on the morning of the event, the actors receive their roles and the directors arrive to begin rehearsal. Less than 12 hours later, they must be ready to perform in front of a live audience.
