Richard Norton, an Australian martial artist, screen actor and stunt coordinator who trained celebrities like Charlize Theron and Liam Neeson for film stunts, died in Melbourne. He was 75. Norton’s wife, Judy Green, confirmed the news on Instagram. A cause of death was not immediately available.

“I am numb and devastated, I have no words,” Green wrote. “I have lost my everything. I know there is, and will be lots of love and shock that we have lost this incredible human being. The love of my life. I’m using this time to come to terms with my great loss.”

In recent years, Norton’s fight choreographer credits included high-octane tentpoles like “Suicide Squad,” “The Suicide Squad,” “Blacklight” and “X-Men: Dark Phoenix.” Along with coordinating stuntwork on both “Furiosa: A Mad Max Saga” and “Mad Max: Fury Road,” he also played the role of the Prime Imperator, a lead henchman to the villainous Immortan Joe.

“Richard Norton was a wonderfully talented stunt performer, stunt coordinator and actor. He was also f a friend,” director James Gunn wrote in a tribute post Sunday. “I met Richard as the fight choreographer on ‘The Suicide Squad’; he choreographed the Harley escape scene, Peacemaker vs. Rick Flag Jr. and more. He was a tough but sweet Australian dude with a hearty laugh and a million stories about his years making movies.”

Norton is also credited for stunts on the 1980 film “The Octagon.” He played the character Slade in “Equalizer 2000.” He was a fight choreographer for “Under the Gun” and a stunt coordinator for “Dream Warrior” and “The New Adventures of Robin Hood.”

Norton’s talents led him to collaborating with many Hollywood actors, such as Anya Taylor-Joy, Jackie Chan, Sophie Turner and Scarlett Johansson. He also trained musicians like Stevie Nicks and ABBA member Agnetha Fältskog; “ABBA: The Movie” was one of his first film jobs. Norton is also credited as the co-creator of a martial arts style deemed “Zen Do Kai.”

Robert Patrick, who has been in the series “1923” and acted in “Equalizer 2000”, shared a video of himself with Norton on Instagram and wrote, “He was an extraordinary individual, a towering figure in the martial arts community, and a contemporary of Chuck Norris.”

“In addition to his impressive career as a highly sought-after bodyguard for rock stars, he made his mark as an accomplished fight coordinator on major films,” Patrick continued. “More than that, he was a wonderful human being, and I feel fortunate to have shared the screen with him in ‘Equalizer 2000.’”

Norton is survived by his wife, Judy.
