PHOTO CALL: Mark Evans and Christopher John O'Neill Join the Book of Mormon Tour

Mark Evans and Christopher John O'Neill have taken over the roles of Elder Price and Elder Cunningham, respectively, in the first national tour of the Tony-winning musical The Book of Mormon.

Evans, a U.K. actor whose credits include Ghost, Wicked and Oklahoma!, and sketch comedy performer O'Neill, step into the leading roles that were first played on tour by Tony Award nominee Gavin Creel and Jared Gertner. Creel and Gertner will open the London production of Book of Mormon, which will begin Feb. 25 at the Prince of Wales Theatre.

"South Park" creators-writers Trey Parker and Matt Stone, and Tony-winning Avenue Q songwriter Robert Lopez collaborated on the script and score to the musical, which earned Tony Awards for Best Book, Best Score and Best Musical.

Co-directed by Parker and Casey Nicholaw, The Book of Mormon opened to critical acclaim March 24, 2011, at the Eugene O'Neill Theatre. Both earned Tony Awards for their work and repeat their duties for the tour.
