LONDON (AP) — Auctioneers overestimated the power of the dark side.An original Darth Vader costume from a "Star Wars" movie did not sell at auction yesterday when no bidder offered to pay the reserve price, Christie's auctioneers said.

The outfit — a jet-black helmet, mask and armor — was expected to sell for between £160,000 and £230,000 ($250,000 to $365,000). The reserve price is confidential but generally it is just under the minimum expected price.

Christie's said bidding stopped at £150,000.

The costume is thought to have been made for "The Empire Strikes Back," the second film in George Lucas's sci-fi series, released in 1980.

The auction house's head of popular culture, Neil Roberts, said the costume is one of the most iconic in the history of cinema.

Christie's did not name the seller, identified only as an American private collector.
