Amanda Seyfried and Nina Dobrev are among the actors who have signed up for a marathon stage play that takes place in 24 hours and raises money for Urban Arts Partnership, which supports arts education in New York City’s public schools.

Seyfried will take part in the 14th annual performance of The 24 Hour Plays on Broadway benefit Nov. 17. The event, touted as an “extreme rite of theater,” has actors, writers and directors writing, directing and performing six original short plays in a 24-hour period.

Quite the undertaking, the marathon begins at 10 p.m. Nov. 16 when six writers, six directors, 24 actors, two musical guests and a production staff gather at New York City’s American Airlines Theatre. After each of the actors share a costume, prop and special skill, their assigned writer must create a ten-minute play by 7 a.m. the following morning. Directors return to read and select their piece and meet with their cast for the first time by 9 a.m. The final pieces will be performed at 8 p.m., interspersed with six musical acts.
