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.
