I was sad when I heard he had passed away. He is one my most favorite actors and he will be missed. He was perfect in the role of Frank Murphy.
He made lots of other great films such as The French Connection, The Seven Ups, 2010 and All That Jazz (okay, it was a bit odd but different). Check out The Seven Ups for an amazing fist fight and car chase with him.
I was writing a screenplay for him to return as a deskbound Captain Frank Murphy but I was too late. He had apparently been sick for a while, having cancer treatment a few years ago. My father said he was a real smoker, loved his tobacco.
R.I.P Roy.
