Bidders must be residents of the United States and willing to undergo a complete background check (which is quite paranoid, considering you PAY for the tickets!)
But anyway, once you win the ticket you can sip champagne December 8th and watch 'Benjamin Button' pretty much before anyone else. If anyone of you plans to bid and win, please let us know ... we'd like to know how it feels!
... and for the extra ebay-experience, here's some more: A Teddy Bear made by Baby Benjamin Button, auctionable with a photo of the kid with David Fincher and Cate Blanchett. Hilarious!
