When the British actress was filming the Roman Polanski-directed movie Carnage she was required to throw up.
The vomit came in an awkward scene where her character is discussing the playground brawling of her on-screen son.
Winslet's family got to witness the act in the flesh.
'My kids came to visit me on set for the vomit day,” the 35 year-old told media before the premiere.
“I am so thrilled that they were there because they literally have not stopped talking about it since. It was hysterical. We were all completely beside ourselves with laughter.'
