For me this will always be Paul Thomas Anderson's masterpiece. A glorious look at the golden age of the other side of Hollywood.
A pool party introduces a lot of the films secondary characters but the best moment is the appearance of Scotty J just as a girl who's overdosed on coke is carried out. His hair is hilariously 70's. He's in a t-shirt about 5 sizes too small. He's clumsy and awkward and doesn't really want to be there. Hot Chocolate's You Sexy Thing kicks off just as he spots the new object of his affections. It's just a perfectly ironic introduction to his character.
Man I miss Philip Seymour Hoffman.
