SARAH JESSICA PARKER and MATTHEW BRODERICK

James Wilkie, five, notices his mum and dad lighting up and constantly questions his parents about what they are doing.

Broderick says, "I used to smoke cigarettes, and I still do, lately. I gave that up a long time ago, but every now and then I will fall off for a week.

"(Sarah Jessica) is worse than me on that. James Wilkie is already curious.

"He'll see a cigarette butt and say, 'What is that? Why do people smoke?' I can just see the little budding gene of a smoker in there."
