The Book of Mormon: Twenty reasons you've got to see it, courtesy the cast and crew

15. All the standards of traditional musicals are still in there somewhere.
"What I love about this show is that it takes conventional aspects of musical comedy and staging and choreographing and interjects really modern sentiment and ideas," Creel says. "I saw it in previews and was completely dazzled. The performance is genius, the writing is fast and the staging is so funny."

14. You're just as likely to cry as to cackle.
"I think the wide range of emotion it gives people is something that surprises them," Henson says. "You will laugh uproariously and then cry and really be affected and touched. That's really exciting for me in a show -- to have that wide range of effect on people -- and I think that's why audiences keep coming back."

13. Setting the controversial concepts to music changes them entirely.
"When you sing these words for the first time instead of reading them, it's all different," says Jared Gertner, who plays Elder Cunningham and starred in the musical's original Broadway run. "Matt and Trey write South Park, and they have these lines you can't believe anyone is writing or saying, but then they have little cartoon children say it and somehow it works. Somehow, when you musicalize these ideas, it taps into a different part of the audience. I don't understand the brilliance, but I respect it."

12. Every once in a while, someone still walks out.
"I saw one, and she kind of looked around like, 'Come on, guys!'" Lopez says. "She made a spectacle and very obviously put her program down into the garbage."

11. The play has widened the doors for musical theater.
"The Book of Mormon has changed the face of American musical theater," Henson says. "I believe the statements and the guts the show has is something people never thought they would see on a Broadway stage, or for us on the touring stage. Hopefully, after this show we will see more. That's what's exciting about theater, when it surprises you and takes you off guard. I think it's made it okay to take chances."
