Charlize Theron and Will Smith literally stopped traffic in Hollywood on Tuesday (11Sep07) when they filmed an argument in the street. The movies stars sent gossip columnists into overdrive when they were spotted screaming at one another on Hollywood Boulevard during filming of new movie John Hancock. Bystanders had no idea the row was being filmed when Theron was heard yelling "It's over" at her co-star. But movie insiders have calmed the fuss, insisting the quarrel was part of the film. John Hancock shooting caused traffic chaos in Hollywood this week (beg10Sep07), shutting down a block of Hollywood Boulevard for three days.
