A turning point in Hoffman's career came with the biographical film "Capote" (2005), which dramatized Truman Capote's experience of writing his true crime novel "In Cold Blood" (1966). Hoffman took the title role for a project that he co-produced and helped come to fruition. Portraying the idiosyncratic writer proved highly demanding, requiring significant weight loss and four months of research – such as watching video clips of Capote to help him affect the author's effeminate voice and mannerisms. Hoffman stated that he was not concerned with perfectly imitating Capote's speech, but he did feel a great duty to "express the vitality and the nuances" of the writer. During filming, he stayed in character constantly so as not to lose the voice and posture: "Otherwise," he explained, "I would give my body a chance to bail on me." "Capote" was released to great acclaim, particularly regarding Hoffman's performance. Many critics commented that the role was designed to win awards, and indeed Hoffman received an Oscar, Golden Globe, Screen Actors Guild Award, BAFTA, and various other critics' awards. In 2006, "Premiere" listed his role in "Capote" as the 35th-greatest movie performance of all time. After the film, several commentators began to describe Hoffman as one of the finest, most ambitious actors of his generation.
