Julianne Moore believes the Hollywood lifestyle can leave people feeling "empty."

The 53-year-old actress stars in David Cronenberg's latest movie Maps to the Stars as ruthless Havana Segrand, a fading star living among the Hollywood elite, and admits the character shows what can go wrong in the movie .

"Oh, I wouldn't say she's a monster, although it's true she does behave monstrously at times. She's one of these creatures that are very common in our industry, in that all of her self-worth and affirmation is projected from outside as opposed to inside. And the longer you live that kind of lifestyle, the more empty you become, until there comes a point when you just implode," she told The Guardian.

Moore - who is married to Bart Freundlich with whom she has son Caleb and daughter Liv - also says the film industry is too age obsessed, something she refuses to subscribe to: "You know, maybe that's a danger in any profession. But in the movie business it's heightened because it's all tied up with your face and how you look and the world's perception of that. But the only people who can affirm you are your family. They are the ones who are close to you. They're the only ones who can really see you."
