 According to director Charles Shyer (qv), in the shot where Alfie  (Jude Law (qv)) punches a car windshield, Law actually cracked the  windshield. Apparently, the actor wasnt able to put as much effort  into punching it until Shyer told him to imagine that it was the  paparazzi. As a result, Law punched so hard that a sledgehammer had  to destroy the cracked windshield.
