Crew members found an unidentified metal object lying in the parking lot of The Green Hornet set in Los Angeles yesterday. Security was alerted and the LAPD bomb squad was sent in. The squad reportedly blew up the object on the spot with a robot. A police spokesman told E! News, “Everything is clear, they only found a smoke detector.” It’s not known whether the stars of the movie, Seth Rogen and Cameron Diaz, were on the set at the time. Earlier this month, a stunt driver, lost control of the Black Beauty car and crashed into the front of the Creative Artists Agency’s head office. Luckily the stuntman escaped injury. The Green Hornet opens December 22, 2010 in theaters.
