Fahrenheit 9/11). Fahrenheit 9/11 Moore's film, Fahrenheit 9/11, released in 2004, examines America in the aftermath of the September 11 attacks, particularly the record of the George W. Bush Administration and alleged links between the families of George W. Bush and Osama bin Laden. Fahrenheit was awarded the Palme d'Or, the top honor at the 2004 Cannes Film Festival; it was the first documentary film to win the prize since 1956. Moore later announced that Fahrenheit 9/11 would not be in consideration for the 2005 Academy Award for Documentary Feature, but instead for the Academy Award for Best Picture. He stated he wanted the movie to be seen by a few million more people via television broadcast prior to Election Day. According to Moore, "Academy rules forbid the airing of a documentary on television within nine months of its theatrical release", and since the November 2 election was fewer than nine months after the film's release, it would have been disqualified for the Documentary Oscar. Regardless, Fahrenheit did not receive an Oscar nomination for Best Picture. The title of the film alludes to the classic book Fahrenheit 451 about a future totalitarian state in which books are banned; according to the book, paper begins to burn at . The pre-release subtitle of the film confirms the allusion: "The temperature at which freedom burns." As of August 2012, Fahrenheit 9/11 is the highest-grossing documentary of all time, taking in over US$200 million worldwide, including United States box office revenue of almost US$120 million. In February 2011, Moore sued producers Bob and Harvey Weinstein for US$2.7 million in unpaid profits from the film, claiming they used "Hollywood accounting tricks" to avoid paying him the money. In February 2012, Moore and the Weinsteins informed the court that they had settled their dispute. Sicko Moore directed the 2007 film, Sicko, about the American health care system, focusing particularly on the managed-care and pharmaceutical industries. At least four major pharmaceutical companies—Pfizer, Eli Lilly, AstraZeneca, and GlaxoSmithKline—ordered their employees not to grant any interviews or assist Moore. According to Moore in a letter on his website, "roads that often surprise us and lead us to new ideas—and challenge us to reconsider the ones we began with have caused some minor delays." The film premiered at the Cannes Film Festival on May 19, 2007, receiving a lengthy standing ovation, and was released in the U.S. and Canada
