The 21-year-old star, who was cast in `Harry Potter` movies at the age of nine, feels acting does not come naturally to him.
Radcliffe insists he and his co-actors - Rupert Grint and Emma Watson were included for the roles because of their appearances, rather than their talent, reported Contactmusic.
"I think there`s a perception that we got the parts because we looked right. I think that`s probably quite fair.
"Also, acting is something that I don`t necessarily think comes naturally to me. Certainly not as natural as it does to, say, Haley Joel Osment or Dakota Fanning, who were just giving full-blown adult performances at the age of 10."
Despite Radcliffe`s acting insecurity, the cast and the crew praises his performances.
"On the first day of shooting the very first film Dan had these coloured contact lenses in. And they were causing him so much pain but he never complained.
"There are people who have nowhere near his talent or celebrity who don`t show that commitment. I think he missed maybe two or three days through sickness in the entire eight films," said Producer David Heyman.
