The three-year-old STAR WARS fanatic baffled airport security when he insisted he was Luke and Bettany was super-villain DARTH VADER.

Bettany's wife and Stellan's mother JENNIFER CONNELLY reveals, "They were in Nice and they were coming home and they got to the airport and went to passport control and Stellan has an American passport and Paul has a British passport.

"Stellan's photo was taken when he was about a week old and he's now three years old, so it's completely unrecognisable.

"So they march up to passport control and Stellan announces, 'I'm Luke,' and the woman at passport control goes, 'Excuse me.'

"She brings someone else over and they ask again, 'Who is this person? Is this your father?' and he goes, 'No, that's not my daddy.' And then they call the police.

"They said, 'Well, who is this man? What is this man's name?' and he says, 'That's Darth Vader!'

"It so happened that they were , like, probably the only three people in the world who hadn't seen Star Wars, so this went on for a little while before someone finally figured it out."
