Cliff Simon, who played the villainous Ba'al in Stargate SG-1 and Stargate: Continuum, died at the age of 58.

The announcement came from his wife, Colette Simon, who posted the news on Facebook. "It is with unimaginable heartbreak that I am sharing with you that my beloved husband, Cliff Simon, passed away at 12:30pm on Tuesday March 9, 2021. He was at Topanga Beach, California and sadly passed away after a tragic kiteboarding accident," she wrote.

"He was known to most of you on this page as the villain you loved to hate, Ba'al, from Stargate SG-1," she continued. "But as he said, 'acting is what I do, it's only a part of who I am.' And he was SO much more – a true original, an adventurer, a sailor, swimmer, dancer, actor, author. There is a gaping hole where he once stood on this earth. He was loved by too many to mention and had a great impact on so many lives. He was an amazing and much loved brother, uncle, nephew, cousin and friend."

Simon's other credits included The Americans, NCIS and 24. He also did voice work for the video games The Order: 1886 and Metal Gear Solid V: The Phantom Pain. Aside from acting, he was a skilled swimmer, earning a place on the British International Olympic team in 1984. He also served in the South African Air Force.

"A small saving grace to this tragedy is that he was doing one of the things he loved most and passed away on the beach near the water, which was his temple," his wife added.
