The full list of 570 available items hasn't yet been released, but each item teased out has been pretty exciting, like a full Predator costume and a Captain America shield.
The auction kicks off on September 27 at London's BFI IMAX and it demands that you create a crazy list of the geek fantasy collectibles they're hawking, like a clapboard from Jaws, Mulder and Scully's ID badges from The X-Files, and a Sloth mask from The Goonies.
But if you don't have the thousands of dollars it'll take to buy the auction's best items, maybe just check out the Prop Store exhibition before the auction, which is free and open to the public. It's almost as good as jumping out of the broom closet at work with a Sloth mask on. Almost.
