Pixar Animation mastermind John Lasseter says the company has no environmental agenda, but with "Cars 2," the blockbuster outfit does tap into today's eco-mindedness with a plot driven by oil vs. a cleaner alternative. Debuting in U.S. theaters Friday, "Cars 2" sends race car Lightning McQueen (voiced by Owen Wilson) on a World Grand Prix circuit whose organizer fuels the vehicles with a green alternative called Allinol, prompting the bad guys to try to discredit the new power supply that threatens traditional gasoline.
