Every year, like clockwork, Broadway ticket sales crash after the holidays. According to the New York Times, over the first half of January, box-office grosses dropped by 50 percent for “Annie,” “Chicago,” “Mamma Mia!,” “Mary Poppins,” “Spider-Man: Turn Off the Dark” and “The Phantom of the Opera” from their December high. Everyone seems to be suffering at the box office except “Book of Mormon” which has already grossed $200 million and is bringing in $19 million per month. Other Broadway blockbusters including “Wicked” and “The Lion King” had a smaller rate of decline. Expect to see more from the hilarious musical, the show is about to go into production in London and film producer Scott Rudin has the rights to a “Book of Mormon” movie.
