"Many people do feel stuck in their lives and they don't know how to make a change. And not only that, they don't want to address it because it's too scary." It's hard to believe, I say, that a woman with such a diverse career and life as Diane – a woman who's not only appeared in over 45 films but written seven books (her latest, The House that Pinterest Built , out in October, is about her new home), been a photographer, had those high-profile relationships, started a wine label and brought up two kids by herself – could possibly identify with "stuck". She seems always to be embarking on a new adventure. She looks away and looks down with a smile. "Yeah, but I'm not really. Not really."
