The Brit admits the excess vomit made the set rather unpleasant to work on, but she enjoyed every moment of it.

She tells People magazine, "I'm actually quite proud of my vomiting! It was everywhere: in my hair, down my cleavage, and I'd go home every night totally disgusting and smelling of sick, but I loved it."

The film, directed by Roman Polanski, is based on the hit Broadway play God of Carnage.
