I came across this image of Jack Nance and David Lynch making Eraserhead at Mostly Forbidden Zone, and it filled me with happiness!
I really like how David Lynch looks here. It's such a fashionable, urbane look totally at odds with the "I'm slightly deranged, dontcha know" thing he's had going on since Twin Peaks or so. He actually looks rather dashing!
Jack Nance is so cool in this movie. He is the epitome of nervy, twitchy New Wave masculinity. Did Tim Finn swipe his look from Jack? You be the judge (second from left, for those what don't know):
