Some of the greatest writers were often the most tortured souls. Philip Seymour Hoffman parlays this torment of Breakfast at Tiffany’s author Truman Capote in Bennett Miller’s film, Capote, which looks at the five years during which Capote wrote his most famous novel, In Cold Blood.

The DVD extras highlight Capote’s eerie world. The first feature, Unanswered Prayers, is a short documentary on Capote’s life. It shows Hoffman, Miller, screenwriter Dan Futterman and biographer Gerald Clarke discussing how Capote’s larger-than-life personality masked a painful childhood. The documentary is short and sweet – enlightening without being overbearing.

But the two-part making-of documentary is too drawn-out. We do learn Hoffman lost weight, adopted Capote’s signature high-pitch mumble and practiced his body posture to make Capote come to life. But we’re also forced to endure a producers’ description of the muted colors used to accentuate the stark environment.

Although the features don’t offer much, they do highlight the most important point of the film: The most interesting person in In Cold Blood isn’t even in the book – it’s Capote.
