"Here's what seems to have happened: The actor playing Spider-Man (Reeve Carney or his alternate Matthew James Thomas?) and the actress playing his love interest Mary Jane (Jennifer Damiano) fell into the stage pit an hour or so into the show. According to screenwriter Brian Lynch [on Twitter], 'No joke. No explanation. MJ and Spidey took what seemed to be a planned fall into the stage pit. Then we heard MJ screaming.' "
Someone else who wrote in to Gawker: "Long story short, spiderman fell abt 30 feet INTO THE PIT. As soon as he fell, the lead female character yelled (from the pit) "someone call 9-1-1." I wish I was making this up. When we left there were ambulances and firefighters outside the theater on 43rd."
Just to put this in context, here are the three previous stories about the show on Gawker:
Spider-Man Musical's First Show Goes Splat (rigging falls into the audience, harnesses malfunction)
Curse of the Spider-Man Musical Claims Another Victim (actress gets a concussion)
The Spider-Man Musical Is the Most Dangerous Show on Broadway (dancer breaks both wrists, actor breaks both feet)
Y'all, someone has got to pull the plug on this show. I don't care if they've spent a billion dollars on it--someone is going to get killed.
Update: Actor being treated at hospital after falling from broken rope during 'Spider-Man' preview - New York Times.
