Russell Crowe reportedly flew "into a rage" in a stunning meltdown in which he was "screaming at people" before "storming off".
The Kiwi actor was at a Q&A event in New York, taking part in a panel discussion about his new TV series The Loudest Voice in which he plays the late Fox News chairman Roger Ailes.
According to the New York Post, he lost his cool when the event's producers wanted the host Ricky Camilleri to introduce Crowe in a way that would cast Ailes - who resigned from Fox News in 2016 following sexual harassment allegations - in a bad light.
A source said: "It was harmless, but Russell threw himself into a rage as soon as he heard it. It had not been preapproved by his people. He refused to walk out on the stage. He was screaming at people and then just stormed out onto the street."
According to the Post, Crowe returned after storming out to do a press interview in the basement, where Camilleri and a producer attempted to apologise to him but Crowe was reportedly still fuming and "completely unloaded" on Camilleri.
