Deadwood actor Powers Boothe died of a heart attack, according to his death certificate obtained by TMZ.
The Emmy award-winning actor suffered a cardiopulmonary arrest on May 14 after battling pancreatic cancer for the past 6 months. The certificate names his wife, Pamela, as his surviving relative and informant.
Boothe was buried in a private service in his home state of Texas. He was born and raised in the small town of Snyder (population: 11,000, give or take), where he was the youngest of three sons to a sharecropper farmer. In west Texas, he saw a future in either oil or farming, and opted instead to go to college – becoming the first person in his family to do so.
Boothe made his national breakthrough in 1980 starring as a true-life demagogue and cult-leader in the CBS docudrama Guyana Tragedy: The Story of Jim Jones. He went on to star in films like Red Dawn, Sin City and The Avengers, as well as TV shows like HBO’s Deadwood.
His death first broke online through longtime friend Beau Bridges, who tweeted: “It’s with great sadness that I mourn the passing of my friend Powers Boothe. A dear friend, great actor, devoted father & husband.”
