‘American Idol’ Alum Constantine Maroulis Lands ‘Jekyll & Hyde’ Lead

“Idol” runner-up will play both both the doctor and the monster he spawns in Robert Louis Stevenson stage adaptation

"American Idol" veteran Constantine Maroulis is about to have a big-time personality crisis.

Former American Idol contestant Constantine Maroulis will star in Jekyll and Hyde on Broadway

Maroulis — who placed sixth in the fourth season of the show — has landed the starring dual role in the upcoming musical production of "Jekyll & Hyde." Maroulis will play both Dr. Henry Jekyll and Edward Hyde in the musical based on the Robert Louis Stevenson story, which begins a 25-week national tour at the Civic Theatre in San Diego, Calif. on October 2 before beginning a limited Broadway run in Spring 2013.

The show, which bowed on Broadway in 1997 and played for four years, was written by Tony-nominated composer Frank Wildhorn, with  a book by Oscar and Grammy winner Leslie Bricusse. Jeff Calhoun, whose credits include "High School Musical: On Tour!" and "Big River" on Broadway, will direct and choreograph the revival. Nederlander Presentations will produce.

"Jekyll & Hyde," which has toured worldwide, includes such songs as "This Is the Moment," "A New Life" and "Someone Like You."

Maroulis is no stranger to musical theater: the 36-year-old belter, known for his dark, untamed mane, received a best actor Tony Award nomination for his performance in "Rock of Ages" (he'll also play a small role in the upcoming big-screen version, starring Tom Cruise), and has performed in stage presentations of "The Wedding Singer" and "Rent."

The musical will mark a return to Broadway for Wildhorn, whose latest musical, "Bonnie & Clyde," closed up in December after a mere 36 performances.
