Some stars toned down the glitz at last night’s Academy Awards ceremony in acknowledgement of the war in Iraq, while others toned down their energy consumption, arriving at the event in gas-electric hybrid cars instead of gas-guzzling stretch limos. Actress Cameron Diaz was chauffeured to the Oscars in her own Toyota Prius. “I drive it every day,” she told reporters. Harrison Ford, Susan Sarandon, Tim Robbins, and Robin Williams also made the trip in Priuses, courtesy of Global Green USA.
