A fire erupted at the Big Apple’s Eugene O’Neill Theatre -- the home of the hit play "The Book of Mormon" -- Monday morning, according to FDNY officials. More than 60 units and nearly 200 first responders rushed to the Broadway venue starting around 10 a.m. to battle the three-alarm blaze in Midtown Manhattan, the FDNY said. No injuries were immediately reported and the effort to control the blaze is ongoing.
