Frightful nights at Madame Tussauds After Dark

If you love being freaked out by those Madame Tussauds wax figures, you’re in luck.

Starting tonight, for eight nights only, the Times Square repository of eerily still celebs will stay open late, transforming for the second year into a creepy haunted house.

Madame Tussauds After Dark has organic origins, said Kathy Bagshaw, the museum’s director of operations.

“It all started because people used to ask us what is it like working here and being in the venue at night when we turn the lights off,” she said. “Is it spooky because of the wax figures?”

The exhibit begins with a “4-D” movie event, in which the audience is shown “found footage” of a terrifying after-hours incident that’s accompanied by bursts of air brushing into your legs, sudden back pokes and other creepy effects.

From there, you and a group are led through various darkened or strobe-lit rooms in which actors hide among the museum’s renderings of famous personalities, bursting out and startling you at unexpected times.

It all makes for an unusual, and unusually effective, haunted setting.

“I think wax figures by night scare everybody, Bagshaw said. “You’re never quite sure who’s real and who’s not.”

If you go: Madame Tussauds After Dark runs from 9 p.m.-1 a.m., Thursday through Sunday and Oct. 28-31. $23.95 before 11 p.m.; $21.78 after 11 p.m.
