Yeh I was so confused when I watched the (without knowing) extended version. I remember being told there were no 'talking heads'.
Also, it wasn't editing amazingly. You'd be half way through a really heated/emotional part, then it'd suddenly cut to silence as the talking head is about to speak. (I make it sound like that guy out of Art Attack...? I bet that's a reference that'll fall flat on its face
)
