Emily Blunt has strict rules about starring opposite her husband in a movie.
Blunt insists she wouldn't take part in a romantic storyline with John Krasinski as she wouldn't want to put their chemistry "up for public consumption".
She told C magazine: "I think we would prefer it to be something where we're not married or boyfriend and girlfriend.
"Our chemistry is not up for public consumption. We'd like to do a play. That would be cool."
Meanwhile, the 33-year-old actress - who has two-year-old daughter Hazel with John and another baby on the way - previously claimed Hollywood makes movies for 14-year-old boys.
She said: "I think people are making films that are targeted towards one type of audience, which is 14-year-old boys.
"You hear this a lot, 'We've gotta get the 14-year-old boys in'. I think there's a large number of the population who aren't 14 or male. I think that's becoming less of the target because I don't think you can crunch numbers on what people are going to respond to."
