Charlize Theron loves working with Will Smith

Hollywood superstar Charlize Theron says she love working with Will Smith - and even gets star struck when she's in his presence.

She said: "I would make a film about a tape recorder with Will Smith! I love working with him, he's an incredible actor."

Meanwhile, the 'Head in the Clouds' actress, 32, reckons smoking has been the key to her success - and believes her unhealthy habit was the main reason she landed a starring role in upcoming Paul Haggis directed movie 'In the Valley of Elah'.

She said: "I still smoke, occasionally. But it led to a role in my new film, 'In the Valley of Elah'

"I kept on running into writer and director Paul Haggis when we were at an awards event. He was there for his film 'Crash' and I was there for 'North Country'. We were the only two losers in an alley, smoking. He said, 'I'm going to write a film for you.' And he did."
