Josh Radnor of How I Met Your Mother and F. Murray Abraham of Homeland are the latest actors to volunteer putting themselves in an unfamiliar place onstage with White Rabbit Red Rabbit.

The play requires no set or director and the actors don’t read the script until they are onstage for the first time. Then they are asked never to perform it again.

The play, by Iranian playwright Nassim Soleimanpour, has been performed every Monday in New York at the Westside Theatre. Soleimanpour wrote the play after being barred from leaving his native country because of his status as a conscientious objector.

Abraham, last on Broadway in It’s Only A Play, is set for July 18. Radnor, last on Broadway in Disgraced, gets his chance July 25.

Some celebs who have tackled the work include Whoopi Goldberg, Nathan Lane, Brian Dennehy, Christine Baranski, Alan Cumming, Ramin Karimloo, Andrea Martin, Marin Mazzie, Donna Murphy, David Hyde Pierce and George Takei.

The play had its world premiere in 2011 at the Edinburgh Festival Fringe and has since been performed across the world.

A portion of the play’s profits will go to PEN International, an association of writers working to promote literature and defend freedom of expression around the world.
