A group of six US movie studios have launched legal action against two Beijing shops accused of selling pirated DVDs. The studios are seeking damages and an apology, the Wall Street Journal reported. The suit is yet another step in a campaign to stop, or slow down, the flow of fake products in China. "The mountain we are climbing is high, and the pirates are busy building the mountain higher every day," said Motion Picture Association lawyer Frank Rittman. The MPA filed the suit on behalf of Columbia Pictures, Disney, Paramount, Twentieth Century Fox, Universal and Warner Bros. The lawsuits target two shops accused of selling 16 to 17 titles.
