While capturing those legendary performances was one thing, compiling all of them into the film was the true challenge.
Editing is the filmmaking itself, and so I've always been involved in the editing from the very, very beginning. It had to be just felt. Sometimes you couldn't really express it in words. It just felt more comfortable or it felt like it flowed better visually, or moved in tone. And it's something I can't define, but it's nerve-wracking and its anxiety-producing—but it's what we like to do.
