Entertainment lawyer Bert Fields, known for his work with A-list celebrity clients, passed away Sunday at the age of 93 in his California home.

Fields' law firm, Greenberg Glusker Fields Claman & Machtinger, announced the attorney's death on August 8 via a statement.

"Most of his entire career was spent at Greenberg Glusker Fields Claman & Machtinger, a firm that he helped to turn into a Hollywood behemoth. Along with the industry-shaping deals that he helped negotiate, this American legal legend tried numerous landmark cases in the entertainment, sports, and communications industries, and he has been the subject of several personal profiles in magazines and newspapers," the statement read. 

Fields is said to have been suffering from "long-term neurological effects of COVID-19" prior to his passing, firm spokesman Seth Horowitz told the Associated Press.

Fields' most notable clients included Tom Cruise, Michael Jackson, and the Beatles, as well as Harvey and Bob Weinstein. The longtime attorney was known for his keen wit as well as his oral advocacy in the courtroom. 

"He was a brilliant renaissance man… and, yet, he still had time to be an incredible, kind friend. He was my daughter’s godfather and the officiant at her wedding. He was fiercely loyal to his core. He was a true gentleman and I have never known, nor will I know, anyone like him. … I will miss him more than words can express," said actor Dustin Hoffman in the press release.

Outside the courtroom, Fields was a published author of several books on William Shakespeare and King Richard III, where he demonstrated his deep love for history. 

"Bert Fields was a heavyweight. He accomplished it all with dignity and gusto and his indomitable zest for life and adventure. I had the honor and privilege of knowing this remarkable man and, for that, I will be forever grateful," said producer Jerry Bruckheimer said in the statement.
