Very sad to hear that Graham Greene passed away. He was so great in so many roles, for so many years.
What's irritating to me, though, is I've read three different articles about his death and career now... (Of course they all mention Dances With Wolves. But he did so much more than that!) And none of them mention Longmire - though he was such a good villain on that show!
Usually Greene played good guys in the other movie and TV roles I saw him in over the years. But he was positively menacing on Longmire - and he seemed to enjoy playing Malachi.
He will be missed.
