Alfred Hitchcock was not known as the Master of Comedy, though he did appreciate dark humor. Since he’s not with us anymore, it is now up to you to see the hilarious adaptation of Hitch’s “The 39 Steps,” now on stage at Indiana Repertory Theatre.

A UK hit by Patrick Barlow from a concept by Simon Corble and Nobby Dimon, based on the Hitchcock film based on the novel by John Buchan, IRT artistic director Benjamin Hanna brings the story to life with its cast of four. Jürgen Hooper plays our central character, Richard Hannay; Tyler Meredith portrays women important to the plot; and all other roles fall to a couple of clowns – seriously, they are billed as Clown 1 and Clown 2 – exuberantly played by Ema Zivkovic and Michael Stewart Allen.

Hannay is an ordinary man living in 1930s London, feeling bored and unsatisfied with life. Fate is certainly about to fix that! During a theatre show featuring the feats of Mister Memory, a mysterious woman with a German accent sits next to Hannay, fires a pistol, and insists on going home with him. The next day, Hannay is on a train for Scotland, evading the police as he is wanted for murder, knowing just enough about a plot of international espionage to get him in even deeper trouble.

The above plot is Hitchcock’s contribution (from Buchan’s book), the rest is non-stop silliness inspired by English theatre traditions (like commedia del arte meets Monty Python) with various props in trunks, the trunks themselves, doors and windows and such on movable frames – plus inventive uses for a ladder – to enact the movie in the most funny way possible. Along the way, look for references to some of Hitch’s other thrillers.

Hooper and Meredith both charm, excellently handling the elements of both romantic mystery and farce. Zivkovic and Allen’s antics, as well as their turns as key characters, are sharply done.

Not wishing anyone ill, but notable local talents Frankie Bolda and Jay Hemphill are the understudies, and we’re sure they are well up to the task.

The Hitchcockian hilarity of “The 39 Steps” runs through Oct. 12 at 140 W. Washington St., in the heart of downtown Indianapolis. Get info and tickets at irtlive.com.
