Actress Thandiwe Newton has been axed from the new Magic Mike movie after an explosive fight with Channing Tatum - about Will Smith's Oscars slap.
Witnesses told The Sun that the fight escalated to "astonishing" levels before Tatum drove off in a car.
Now executives have postponed filming and re-cast Salma Hayek in Thandiwe's role after 11 days of filming in London.
Newton is reportedly planning to sue studio chiefs at Warner Bros, but sources claim her position is "untenable" after the fight became "unimaginably vicious".
The feud was sparked by a disagreement about Will Smith hitting Chris Rock on stage at last month's Oscars ceremony.
One insider said he saw the pair arguing on set in London, where they have been snapped filming Magic Mike's Last Dance.
"Channing Tatum is the producer and number one on set. Thandiwe Newton is the number-two star. But 11 days into shooting and it's all over," they said.
"They fell out over the debacle at the Oscars. I was on set. I watched her and watched him. They were in and out of the house where we were filming having this confrontation.
"I've watched her have a go at the first assistant director, her costume girl. She's always ranting and raving about something."
A spokesperson for Warner Bros said: "Thandiwe Newton has made the difficult decision to step away from the production of Warner Bros Pictures' Magic Mike's Last Dance to deal with family matters."
Magic Mike has been one of the most successful film franchises of recent years, raking in millions, inspiring a live stage show and propelling Tatum to superstardom.
