Daniel Radcliffe doesn’t act when playing Harry Potter, femalefirst.co.uk reports.

The 19-year-old British actor says his abilities were undeveloped when he first took on the role of the boy wizard in Harry Potter and the Philosopher’s Stone and he felt fans wouldn’t like it if he changed his approach in later movies.

He said: “When I started out at the age of 10 or 11, I was essentially saying the lines as I myself would say them. When I became aware that that’s what I was doing, at 13 or 14, it didn’t make sense to change, because it would suddenly be a dramatic shift in the character.”

Radcliffe admits he is very much like his famous character — created in the best-selling children’s book series by J. K. Rowling — and even his mother has noticed the similarities.

He told Parade magazine: “When she read the sixth book she noticed that Harry argues in the kind of irritating, pedantic way that I argue. She thought Harry and I were getting closer and closer together at that point.”
