since this appears to be published fairly recently (at least on yt), i'll share it in case you might not have seen it:

lynch directing mulholland

what gets me about the footage is that i don't know that i've ever seen someone smoking cigarettes as copiously and continuously and conspicuously as lynch. and based on the photo gras shared and the photo i saw of lynch on the set with stanton during the filming of his guitar solo, it seems like only lynch's alter ego has actually ditched the coffin nails.
