It couldn't cast its net over a wide enough audience.

"Spider-Man: Turn Off the Dark," the popular yet beleaguered $75 million Broadway extravaganza marred by injuries and infighting, will close in January and reopen later at a venue in Las Vegas, according to a producer.

"Economically we have a greater opportunity in the Las Vegas market," said producer Jeremiah Harris, who said the show will reopen in 2015. "Over the last week we've finalized all the creative deals, and are in serious negotiations with a venue in Las Vegas."

The show, which opened in June 2011, will close in January to cut losses while taking advantage of holiday-ticket sales.

The musical, produced by Michael Cohl and Mr. Harris, has been running below its "break-even" point for weeks, a person familiar with the matter said. Last week, it grossed $742,595 out of a potential gross of more than $1.5 million, according to research compiled by the Broadway League. The theater was at roughly 75% capacity, with 9,540 tickets sold out of 12,664 seats that week. Mr. Harris said the show "wasn't making any money or losing any money in New York."
