The 22-year-old actor is starring in his first movie - a horror film The Woman in Black - since the Harry Potter franchise. And although he has been learning a lot on set he says he still panics about his own ability from time to time, Contactmusic reported. "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,'" he said. However, the British star admits he gets "fired" up by those who think he will not be able to be a success outside the Harry Potter franchise.
