In an apparent reaction to the posting of high-quality digital prints of Michael Moore's Sicko on several peer-to-peer websites (Moore has suggested that the piracy was undertaken in order to sabotage the film.) the Weinstein Co. announced Tuesday that it will open the film in New York on Friday, a week earlier than originally scheduled, and provide sneak previews in 43 theaters in virtually all the top 30 markets. It will face another strong "message" film -- A Mighty Heart, starring Angelina Jolie as the wife of slain Wall Street Journal reporter Daniel Perle. A standing ovation followed the screening of Sicko at its New York premiere on Monday. Mixed reviews followed on Tuesday. Jack Mathews in the New York Daily News called it "Moore's most assured, least antagonistic and potentially most important film" to date. Gene Seymour in Newsday commented, "What's most striking about Sicko is how composed, even serene it is compared with Michael Moore's previous acts of cinematic insurgency." But the New York Post's lively conservative critic Kyle Smith called it "political slapstick that could have been made by a third Farrelly brother or a fourth Stooge."
