Daniel Radcliffe has said he has fought hard to prove that he is a good actor.
The 24-year-old Harry Potter star was talking to the New York Times.
He told them "I have a massive chip on my shoulder. When you fall into something at age 11 and get paid incredible amounts of money for your entire teenage years for doing a job anyone would want, there is a part of you that thinks everybody is just saying, 'He got there because he fell into it; he's not really an actor'."
He added "I feel it less nowadays. It has taken a long time to feel like I've earned the place that I'm at."
He also said of being a young star and moving out of home when he was 17 "I didn't have that normal teenage period when you build up your friends in your area and you have a social circle.
"Because of the life I've had, I'd grown up quicker than most people. I felt like I was entitled [to live by myself]. I can be honest about this now, because I know my parents know - but I wanted to smoke. I was hiding it like a fiend."
