A sad day for fans of Powers Boothe, as the revered character actor has apparently passed away. The sinister-voiced star was well-remembered for his role as one of Deadwood’s big bads, as well as appearances in everything from Sin City to Marvel’s Agents of S.H.I.E.L.D.

Word of Boothe’s passing spread over social media from actor Beau Bridges, though TVLine formally confirmed with his representative that Boothe passed away of natural causes in his sleep.

Boothe’s first major acting breakout came with an Emmy win for 1980 miniseries Guyana Tragedy: The Story of Jim Jones, with subsequent gigs taking him to HBO’s Philip Marlowe, Private Eye, and later his Deadwood role as Cyrus ‘Cy’ Tolliver. Boothe also appeared as Senator Roark in both Sin City films, along with villainous parts in 24, Nashville, and most recently, The Avengers and Marvel’s Agents of S.H.I.E.L.D. as Hydra turncoat Gideon Malick.

Boothe is now the second notable Deadwood star to pass away before HBO breaks ground on any kind of revival, but best wishes to those mourning his loss.
