More than two years after it opened on Broadway, The Book of Mormon remains one of theatre's hottest tickets — including in Toronto, where one of the musical's touring productions opened Thursday.

As in other locations, the outrageous religious satire has sold out its Toronto run, which ends June 9.

The Tony-winning musical — which follows a pair of naive Mormon missionaries to a remote village in Uganda — is the brainchild of boundary-crossing South Park founders Matt Stone and Trey Parker, who worked with Robert Lopez, one of the creators of the raunchy puppet-musical hit Avenue Q.

In the video above, Christopher John O'Neill and Mark Evans, who star in the Toronto production, talked to CBC's Deana Sumanac about The Book of Mormon's wild success, the universality of Stone and Parker's comedy and backing each other up onstage night after night.
