Film-makers working on the forthcoming James Bond movie Casino Royale wrecked three sports cars worth $900,000 (GBP500,000) in one afternoon. The identical Aston Martin DBS V12 cars were flipped over during the shooting of a high-speed mountain chase. The luxury V12s were created specially for the 007 film, the first to star new Bond Daniel Craig. Automobile experts estimate that if on sale they would retail for $300,000 (GBP165,000) each. An insider tells British newspaper The Sun, "These are easily the most amazing James Bond cars yet. They look incredible and cost a fortune. "Unfortunately, we had to smash three to pieces. And in the style of 007 our stunt driver walked away without a scratch."
