After a stint on the fourth season of American Idol, Constantine Maroulis moved on to Broadway, starring first in The Wedding Singer and then in Rock of Ages, originating the role of wannabe rocker Drew, and earning a Tony Award nomination for Best Actor. Now, Maroulis is kicking off 2012 as nerdy scientist Melvin Ferd the Third in The Toxic Avenger at the Alley Theatre in Houston, Texas. TheaterMania caught up with Maroulis to discuss the show, his experiences with Rock of Ages, and his advice for other reality show contestants.
