An original 1977 Stormtrooper helmet from the "these are not the droids you're looking for" scene in Star Wars is among over 1,800 pieces of movie and TV memorabilia that will be offered in a November auction in London.

The helmet, precisely called a "Sandtrooper" helmet by the auctioneers, was expected to fetch between £250,000 and £500,000 ($312,500 - $625,000), according to Propstore, the organizers of the auction.

Other pieces being listed include the Gladiator arena helmet and mask worn by Russell Crowe, which was expected to sell for up to £200,000 ($262,174), and artwork for the 1971 James Bond film Diamonds Are Forever, which was expected to garner up to £300,000 ($393,220).

Propstore said that the auction will be held November 14-17 at BAFTA 195 Piccadilly in London.
