As the world readies for the premiere of the final Harry Potter film, Harry Potter and the Deathly Hallows Part 2, some creative Potter fans decided to show their love for the series with the help of Broadway's new smash hit The Book of Mormon. The Tony-winning musical's opening song "Hello" features missionaries heading door to door preaching how the show's title "book will change your life." In the hilarious clip Harry and his Hogwarts pals (all played by Billy Elliot's Tessa Netting!) take on "Hello," changing the lyrics to accommodate plenty of Potter references. Harry Potter himself (How to Succeed star Daniel Radcliffe) doesn't actually appear in the clip, but it's still quite magical. Muggles, meet Mormons by clicking below!
