A diamond in the rough - Danger: Diabolik
I remember having a chat with Roman Coppola a few years ago while working on a Target commercial. We both loved this movie. It inspired him to direct an homage in the form of his 2001 movie, CQ. See Diabolik if you haven't already: John Phillip Law's eyes are absolutely mesmerizing. And Terry Thomas is in it.
What more do I have to say?
