The Chronicles Of Narnia: Prince Caspian star BEN BARNES based his character on an unlikely source - controversial British royal Prince Harry.
The 26-year-old is the same age as Harry's elder brother Prince William, but admits that Caspian is more like the younger, more laid-back royal.
He says, "Caspian is not a swashbuckling heroic Prince Charming, but Americans expect somebody like that. Their concept of a Prince is Disney - that's all they know.
"But I've grown up with two princes, one my age, one my younger brother's age. Caspian makes mistakes; Harry goes to a party dressed as a Nazi. Caspian does something heroic; Harry goes and fights for his country without telling anyone.
"I think it's interesting that they are real people, making real decisions about their lives, but they have the responsibility that they may or may not want."
