The makers of American Hustle are being sued for $1 million over a 10-second quote by Jennifer Lawrence about a microwave.
Her character, Rosalyn Rosenfeld, sets the 70s oven on fire with tin foil and in the following rant claims it "takes all of the nutrition out of food".
"It's not b*******, I read it in an article by Paul Brodeur," she tells her husband, played by Christian Bale.
But Mr Brodeur, a real-life journalist who wrote about the possible radiation hazards of microwaves in the 70s, said he never made that particular claim.
He has filed a lawsuit demanding $1 million (NZ$1.3m) in damages for defamation, saying the film attributes his name to a scientifically unsupportable statement about "taking nutrition out of food", ABC News reported.
