Mahoney, as previously reported, departed the production due to a death in his family.
Directed by ensemble member Amy Morton, the production also features Ian Barford, Yasen Peyankov, Scott Jaeck and Logan Vaughn. Penelope will begin performances Dec. 1 and officially open Dec. 11.
"On a sun-scorched island off the coast of Greece, beautiful Penelope awaits the return of her husband from war," according to Steppenwolf. "Beneath her window, four Speedo-clad men camp in an empty swimming pool, a cock-eyed internment where both provisions and time are running low. Locked in a do-or-die competition to win Penelope’s love, they preen and posture and connive in a last ditch effort to cheat a grisly fate."
