LOS ANGELES (Variety.com) - Powers Boothe, a character actor on the small and big screen, died Sunday in Los Angeles. He was 68.

Boothe died in his sleep Sunday morning of natural causes, his rep tells Variety.

Boothe appeared in several comic book shows and movies, portraying Senator Roark in “Sin City” and its sequel “Sin City: A Dame to Kill For.” He also had a small role in “The Avengers.”

He also played Gideon Malick for eleven episodes on “Marvel’s Agents of S.H.I.E.L.D.” As a voice actor, he voiced Gorilla Grodd and Red Tornado on the animated “Justice League” series.

His talents weren’t only limited to genre material. He played former mayor Lamar Wyatt on 26 episodes of the country drama “Nashville,” as well as Judge “Wall” Hatfield on “Hatfields & McCoys.” Prior to that, he played saloon owner Cy Tolliver on “Deadwood” and Vice President Daniels on “24.”

In 1980, Boothe took home the Emmy for lead actor in a limited series or special for playing infamous cult leader Jim Jones in “Guyana Tragedy: The Story of Jim Jones.”

According to reps, there will be a private service held in Texas where he was from. A memorial celebration in his honor is being considered for a future date. Donations can be made to the Gary Sinise Foundation, which honors the nation’s defenders, veterans, first responders, their families and those in need.

Fans, friends and colleagues took to social media overnight to share their condolences:

Powers Boothe “spoiled” countless TV shows and movies by being a “surprise” bad guy, but was always so great I didn’t care. #RIP — Daniel Fienberg (@TheFienPrint) May 15, 2017

I was on "24" with Powers Boothe. Every word this great, oldschool actor spoke on camera sounded like a first time utterance. He died today. pic.twitter.com/jNb2NNGOCs — Peter MacNicol (@PeterMacNicol1) May 15, 2017
