Kate Winslet's children loved watching her film a projectile vomiting scene for her latest movie.

The British actress brought her children Mia, 10, and seven-year-old Joe on to the set of 'Carnage' while she worked on a scene where her character throws up all over a collection of rare art books and the kids haven't stopped talking about it since.

Kate said: "My kids came to work for the vomit day, and I am so thrilled that they were there because they literally have not stopped talking about it since. It was hysterical."

However, Kate's co-star John C. Reilly was not so impresses as he and actress Jodie Foster were left to clean up the mess.

He explained: "While Kate was the one who threw up, Jodie and I had to clean up the vomit, so we had the more disgusting involvement with the vomit."

The new movie was directed in Paris by Roman Polanski - who is restricted by an Interpol warrant for extradition to the United States to face sentencing for having sex with a 13-year-old girl in 1977 - but Kate was quick to praise the filmmaker's work.

She said: "If Roman Polanski invites you to join in any project, you really don't say no. I had seen the play in New York so I was already very much a fan on the piece. I just felt extremely fortunate to be included."
