Alec Baldwin has laid into Harvey Weinstein during an angry tirade after the Hollywood producer refused to appear in the actor's documentary.
The American star was angered when Weinstein, who produced Lord Of The Rings, would not take part in the film Baldwin is making in Cannes about movie financing.
The Hollywood Reporter said Baldwin was furious when he arrived with fiancee Hilaria Thomas at the Calvin Klein IFP party in the French Riviera resort.
Seeing some people he knew, he walked into the centre of a room filled with models, celebrities and business people, as well as journalists, and started criticising Weinstein.
"I don't care who knows," he is reported to have said. "After the success he had at Cannes last year and all the f****** Oscars, he's still a f****** douche bag. I can't believe it."
Baldwin was upset that Weinstein opted out of participating in Seduced And Abandoned, the Cannes documentary he is shooting with director James Toback.
It is thought the film started as a "mockumentary" but quickly turned into a serious piece about financing films at the festival, with Francis Ford Coppola, Nicole Kidman, Roman Polanski and Marion Cotillard doing real interviews for it.
Apparently, no one would agree to be in a mockumentary, so Baldwin and Toback revised the context, according to The Hollywood Reporter.
According to the magazine, a source close to the actor claimed that Baldwin actually said Weinstein, who unveiled footage from Quentin Tarantino's Django Unchained and Paul Thomas Anderson's The Master at Cannes, "was an a-hole, not a d-bag".
Baldwin has been in town supporting Rise Of The Guardians and has made a number of red carpet appearances with his fiancee.
