New York ( CNN ) -- The stage musical `` Spider-Man : Turn Off the Dark '' will have new safety protocols when it reopens Wednesday night , following an accident in which a performer fell and suffered serious injuries during a preview , officials said . Christopher Tierney , 31 , is listed in serious condition , said Bellevue Hospital spokesman Steven Bohlen . Jonathan Dealwis , a tourist from New Zealand who was in the audience , said Tierney fell `` about 6 meters , '' or about 20 feet , Monday night . Reeve Carney is the actor who plays Spider-Man , but nine people perform Spider-Man 's stunts when the character is masked , according to show spokesman Jaron Caldwell . Dealwis said the accident happened near the end of the show . `` Spider-Man was on a bridge , and Mary Jane was dangling from it , '' Dealwis said . `` I think he was meant to sort of swoop over there , but he just fell off . ... The harness , you could see it just flick off his back and fly backward . '' Afterward , Dealwis said , `` it just went black , and the producer came on and said we 're going to pause for a moment . You could hear Mary Jane weeping . '' A producer then came out and said the show was over , Dealwis said . Some people `` clapped awkwardly , '' and one girl `` laughed mockingly , '' drawing `` disapproving glances '' from others . Dealwis said the performer was wheeled away in a neck brace and was alert when he was taken to Bellevue Hospital . Rick Miramontez , another spokesman for the show , issued a statement confirming that the performer fell from a platform and the show was stopped . `` All signs were good as he was taken to the hospital for observation , '' said Miramontez . Wednesday 's matinee performance was postponed after the incident , Miramontez said , but all subsequent performances will proceed as scheduled . The Spider-Man company met Tuesday with officials from the Occupational Safety and Health Administration , Actors Equity and the New York State Department of Labor to discuss additional safety protocols , he said . The new unspecified measures will be enacted immediately , he added . Show director Julie Taymor said the accident was `` obviously heartbreaking for our entire team and , of course , to me personally . '' `` I am so thankful that Chris is going to be all right and is in great spirits , '' Taymor said in a statement Tuesday . `` Nothing is more important than the safety of our Spider-Man family and we 'll continue to do everything in our power to protect the cast and crew . '' The show , with music and lyrics by U2 's Bono and The Edge , is the most expensive in Broadway history , but production has been beset by cast injuries and technical problems . CNN 's John Roberts , Ethel Bass and Logan Burruss contributed to this report .
