Josh Gad ("The Daily Show with Jon Stewart") and Andrew Rannells (Jersey Boys) star as an unlikely pair of Mormon missionaries who venture from Salt Lake City to AIDS-ravaged Uganda in the hopes of converting villagers with the story of Joseph Smith and the founding of the Mormon Church. The problem is: Only one of them has actually read the book. Broadway previews began Feb. 24.

Parker co-directs with Tony Award nominee Casey Nicholaw (The Drowsy Chaperone, Spamalot), who also choreographs. Book, music and lyrics are by Parker, Stone and Lopez.

Here is a look at the opening night:
