From Atlantic Refugees:
JC: he yelled almost all of his lines
Robert Duvall in Apocalypse Now, Dennis Hopper in Blue Velvet...it's a style.
He's a villain that Dickens might have conceived, if he wrote for multimilliondollar superproductions, and he embodies the theme of abandonment--by his parents, by the city, by his partner (Max Schreck), by his own gang. It's a sad, bitter and at the same time blackly comic role. That dapper stuff, it's as dull as dishwater without the theme of abandonment.
Actually, Daniel Waters' original script developed that further...but it was cut. Haven't heard of a Waters script that wasn't cut. I think that means something.
