The 39 Steps (play)
The play involves four actors performing the a version of Hitchcock's film, which requires the actors to make quick character changes and to occasionally play multiple characters at once.
In 2005, Patrick Barlow rewrote the script, keeping most of the original concepts, but borrowing more heavily from the Hitchcock film. Barlow's re-adapation transferred to London's West End in August 2006 and has since been performed throughout the world.
