I am so, so saddened to learn of the death of Philip Seymour Hoffman, one of our finest actors and one of my personal favorites. Although it wasn't quite his debut film, I first saw him in Scent of a Woman in 1992, where he played a young prep school punk. Hoffman really resonated with me for the first time in Paul Thomas Anderson's Magnolia (1999) and was a frequent actor in many of Anderson's films, most recently in The Master (2012), in which he was absolutely brilliant.
Pick your film - Magnolia, Capote, The Master, Before the Devil Knows You're Dead, Doubt, and many, many others. I will miss him greatly.
