Russell Crowe says celebrity culture is an "unfortunate byproduct" of being an actor.

The Hollywood star - who has children Charles, six, and four-year-old Tennyson with his wife, singer-and-actress Danielle Spencer - has no interest in being famous and thinks society's obsession with people in the public eye is detrimental to the movie-making industry.

He said: "Some people believe celebrity is a power that should be used. Ultimately, your dollars are more powerful. I'm famous for making movies. Celebrity just happens to be an unfortunate byproduct of what I do. Whatever used to be called mystery, you're not allowed to have that anymore. So there's a whole bunch of blank space that's filled in with stuff that fills up pages of newspapers. Which is not real, and you know it's not real, and I know it's not real. And readers don't really care because that's what they're interested in."

The 46-year-old star - whose new film is thriller 'The Next Three Days', a remake of the 2007 French film 'Pour Elle' - has also compared being interviewed by journalists as being the same as "torture".

He added in an interview with the Sydney Morning Herald newspaper: "If I ever was going to torture somebody, I'd put them in a room where they can't leave and have someone new come in every three minutes and ask the same question over a number of days and then weeks."
