Daniel Radcliffe often thinks of himself as a "fraud".
I'm very motivated by the doubts of others. Whenever I hear people talk about the Potter kids as if we are not going to be able to make it out of the series, that really lights a fire under me.
The 22-year-old actor is starring in his first movie, horror flick 'The Woman in Black', since the 'Harry Potter' franchise ended, and although he has been learning a lot on set he admits he still panics about his own ability from time to time.
Daniel - who started playing the schoolboy wizard when he was just 11 -said: "Sometimes I really feel like I'm getting the hang of it, because I never really had a process. My process was mainly that I hit my marks and I said my lines. So I'm kind of trying to find a process that allows me to find a sure fire way into a character, if it doesn't come easily.
"I'm working on that. And there are some days when I feel like, 'Yeah, God, I'm actually learning something, this is great!' And there are some days when I go, 'Oh God, I'm never going to feel good at this. I'm never going to feel like I'm not a fraud.' "
However, the British star admits he gets "fired" up by those who think he will not be able to be a success following on from playing Harry.
In an interview with the new issue of Empire magazine, the 22-year-old actor said: "I'm very motivated by the doubts of others. Whenever I hear people talk about the Potter kids as if we are not going to be able to make it out of the series, that really lights a fire under me."
