You'd probably think nothing of paying $26,000 for a car. How about a hoverboard? Marty McFly's hoverboard from "Back To The Future Part II" is among nearly 400 movie props to be auctioned off in October. USA Today reports, the winning bid is expected to be as much as $26,000 at the October 1st auction being held by Prop Store and Vue Entertainment in London. Arnold Schwartzenegger's biker outfit from "Terminator 2, judgement Day," and the golden ticket from "Willie Wonka And The Chocolate Factory" will also be among the properties offered.
