Theron fell "madly in love" with Smith

Charlize Theron has revealed that she fell "madly in love" with Will Smith on the set of their new movie Hancock.

The pair, who had previously starred in flop movie Bagger Vance together, became firm friends as they filmed the superhero story.

"We didn't get the chance to work that much together and yet it took us all of about five minutes to really fall madly in love with each other," Theron told the Daily Record. "We just hit it off instantly and were always messing around. There was something about me and him. We're very similar people."

Charlize admitted that her success in 2003 movie Monster, for which she received an Academy Award, came in handy during mock arguments with Smith.

"He jokes with me all the time," she explained. "He goes, 'Charlize, this is going to be a little different for you, because people are actually going to see this movie.' Then I'm like, 'I know, Will. But you know what, I have a little statue at home called an Academy Award.'"
