The acclaimed singing actor, who is scheduled to play the role for a year on Broadway, will be seen opposite the Elder Cunningham of Chris O'Neill.
Rouleau told Playbill.com, "I had an amazing year in London ringing doorbells in the West End, but I'm so excited to return to the show on Broadway for the third time. I started in Mormon at The Eugene O'Neill Theatre over four-and-a-half years ago. And while I've been fortunate to play Elder Price across the U.S. and now London, I'm thrilled to return home where it all began."
Rouleau played Emmett in the national tour of Legally Blonde and Woody in Toy Story: The Musical. Television credits include Daddy's Boy in Tina Fey's "Unbreakable Kimmy Schmidt" (Netflix) and the 2012 Tony Awards (CBS).
"South Park" creators-writers Trey Parker and Matt Stone and Tony-winning Avenue Q songwriter Robert Lopez collaborated on the script and score to Mormon, which earned Tony Awards for Best Book, Best Score and Best Musical.
