George Lowe, a veteran voice actor whose credits include the title role in Space Ghost Coast to Coast, died on March 2 at age 67, a spokesperson confirms for TVLine.

Lowe reportedly passed following a long illness, his longtime friend “Marvelous” Marvin Boone shared on Facebook.

Back in July 2023, Space Ghost Coast to Coast contributing writer MC Chris shared with fans concerned about Lowe’s conspicuous absence from social media that the actor had been suffering health problems including an aortic dissection that required intubation twice, and had a nurse looking after him at his home in Florida. “We came close to losing him,” Chris said.

“It’s a sad day at Williams Street,” says Adult Swim president Michael Ouweleen, who was there for Space Ghost‘s launch and knew Lowe for decades. “You all knew him as Space Ghost (and all his other characters), but we knew him as himself, a true character in his own right, one that left an indelible mark on all of us at Adult Swim. Wherever you are, George, we hope you are getting enough oxygen.”

An alumnus of the Radio Engineering Institute of Sarasota, Lowe began his career in the 1980s with occasional voiceover work, before landing the title role in Cartoon Network’s Space Ghost Coast to Coast. A send-up of talk shows that featured live-action celebrity guests, the animated series would run for 10 years and more than 100 episodes, including a move to Adult Swim and a brief revival via Turner Broadcasting’s GameTap online video game service.

His voice acting credits also include The Brak Show, Robot Chicken, Squidbillies and American Dad.
