Also today, we've learned from Universal Pictures Australia that one promotion / competition for the DVD release will be with Australia's local K-Mart stores. When consumers purchase BTTF on DVD from K-Mart, they will have the opportunity to win an 'Airboard' valued at $20,000 (US $10,000). The personal hovercraft was invented in Western Australia, inspired by the hoverboards in Back to the Future Part II. For further information on this prize, visit the Airboard website.
