In an art museum, do we really need to see baby Penguin’s black-wicker pram from “Batman,” Catwoman’s shredded polyurethane cat suit or the fluffy angora sweater used as a fetishistic prop in “Ed Wood”? Such dark or peculiar items are often outward signs of their character’s concealed inner life; but that’s catalog essay interpretation, not exhibition material. You get the feeling they’re only here to satisfy the paying movie fans. Sometimes the display looks like the Arclight Cinema lobby on steroids. Toss in assorted puppets and a few toy-like sculptures, such as a suspended flying-saucer carousel illuminated by black-lights, and the quotient of celebrity self-indulgence climbs.
