Michael Moore's controversial film about the U.S. health care system is apparently all over the Internet, according to Ad Age's Claude Brodesser-Akner, and available for free downloads on peer-to-peer content sites. Obviously, this is a potential box office disaster for Moore and his distributor, The Weinstein Co. (Brodesser-Akner said he was able to download easily.) "Sicko," which opens at the end of the month, has already gotten tons of press, much of it related to Moore's apparently unauthorized trip to Cuba, where he found the health system to be pretty decent.
