The veteran actor won an Emmy award in 1980 for playing cult leader Jim Jones in the TV movie "Guyana Tragedy: The Story of Jim Jones."
He also had memorable roles playing the ruthless saloon owner Cy Tolliver in "Deadwood," the gunman Curly Bill Brocius in "Tombstone" and the corrupt senator in "Sin City."
Met him on Tombstone & married him in True Women. Powers Boothe was a wonderful actor & even better man. Sad month for cowboys. pic.twitter.com/tiQnMqFJjP— Dana Delany (@DanaDelany) May 15, 2017
