The sudden passing of Graham Greene has come as a shock for longtime fans of the actor's excellent body of work. For several decades, he reigned as one of the most prolific Native American actors out there (and certainly one of the greatest on-screen performers in general), playing great parts not just in Western productions but also crime thrillers, action flicks, and comedy-dramas. Still, it's possible that his work in the Western genre is among his best. For some fans, there's one television series that will always best emphasize Greene's talents as an actor, the neo-Western Longmire, where he played the recurring antagonist Malachi Strand for twelve episodes across the final four seasons.
