Hutchinson ? Costumes once worn by Batman and other movie heroes are being featured in a new exhibit at the Kansas Underground Salt Museum.

The attraction shares its climate-controlled space with Underground Vaults and Storage, which stores movie reels and other valuables belonging to movie studios.

And at the storage company’s request, Warner Brothers Entertainment agreed to put some of its memorabilia on display.

The exhibit already includes costumes worn by George Clooney and Arnold Schwarzenegger in the 1997 movie “Batman and Robin,” as they played Batman and Mr. Freeze.

Other costumes on display include Agent Smith from “Matrix,” Snowman from the movie “Jack Frost” and the Superman suit from the television series “Lois and Clark.” A Dorothy machine from “Twister,” the shield worn by Brad Pitt in “Troy” and a James Dean shirt from the 1956 flick “Giant” also are featured.

Linda Schmitt, executive director of the museum’s parent, Reno County Historical Society, said word-of-mouth has been how most people have heard about it. Others have just stumbled onto the underground site.

“I was kind of surprised. We didn’t know anything about it,” said Loren Berendt, of Salina, whose family came to tour a mine recently and wound up in a costume gallery.

Berendt thought it was interesting to learn how salt was mined, but she speculated that her 9-year-old daughter, 11-year-old son and other younger visitors might find the costumes more fascinating.

The museum, which opened in May, has attracted more than 17,000 visitors.

Its double-decker elevator can carry about 14 visitors per car, limiting overall maximum museum attendance to about 560 visitors a day, Schmitt said.

Underground Vaults’ president Lee Spence had talked to studio officials about the new museum and the possibility of lending artifacts for display.

“They came up with this,” said Chris Eden, marketing manager for Underground Vaults, who was pleasantly surprised by the items.

It’s possible that Warner Brothers Entertainment could renew the loan a second year, or even provide additional artifacts.

“We figure this exhibit to be a big draw,” said Lynnette Hilty, the museum’s director of marketing.
