The show also announced that it will celebrate the occasion by launching a daily lottery; a select number of tickets will be made available via a lottery at the box office beginning one hour before curtain call.

The return of Patrick Barlow's Drama Desk Award-winning show officially opened at the Union Square Theatre April 13. The production reunites the play's entire original creative team as well as some of the Broadway cast, and recently celebrated its 100th performance.

"We are thrilled that New York City has welcomed our little-show-that-could back with open arms," said producer Doug Denoff in an earlier press statement. Based on the book by John Buchan and the classic 1935 Alfred Hitchcock film, 39 Steps is a comedic spoof that follows dashing hero Richard Hannay as he races to solve a mystery and clear his name.

The cast of The 39 Steps features original Broadway cast member Arnie Burton as Clown #2, as well as Billy Carter as Clown #1, Broadway vet Robert Petkoff as the dashing hero Richard Hannay and Brittany Vicars as Pamela/Annabella/Margaret in her New York City stage debut.

The creative team includes Tony-nominated writer Patrick Barlow, Tony-nominated director Maria Aitken, Tony-winning lighting designer Kevin Adams, Tony-winning sound designer Mic Pool and Tony-nominated scenic and costume designer Peter McKintosh. The 39 Steps is produced by Douglas Denoff, Mark Leonard, Bruce Robert Harris and Jack W. Batman, Neal Rubinstein, Neil Gooding Productions, J.M. Allain, Corey Brunish/Terrence Cranert, Patrick Blake, Albert and Trudy Kallis, in association with Fiery Angel, London.
