Daniel Radcliffe may be his own toughest critic.
"It’s hard to watch a film like 'Harry Potter and the Half-Blood Prince' because I’m just not very good in it," he said. "I hate it. My acting is very one-note, and I can see I got complacent, and what I was trying to do just didn’t come across."
Radcliffe feels his best performance was "Harry Potter and the Order of the Phoenix" because he could see a progression. And while he may be critical of his acting, "Harry Potter" writer J.K. Rowling was not.
"To my knowledge she was always very happy with the way I played him, but it’s my job to be critical."
However, Radcliffe did disagree with Rowling's revelation that Harry and Hermione should've ended up together in the series, saying, "If Harry and Hermione had ended up together it would have been too conventional and it’s far better to be unorthodox."
Radcliffe also discussed a brief stint of heavy drink between the ages of 18 and 20, including showing up drunk to one "Potter" set.
"I don’t think I was consciously trying to rebel or sabotage everything," he said. "It felt more like there isn’t any blueprint for how to do this, get through this."
Radcliffe also discussed his role--and nudity--in the Broadway play "Equus."
