Daniel Radcliffe: Harry Potter and the Half-Blood Prince (2009)

Radcliffe was only 12 when he played J.K. Rowling's famous wizard for the first time but revealed that he actually hated his performance in one of the franchise's later films.

He said in 2015: "In every movie up to the sixth one, you can see a big step forward in my acting. And then it stopped, or went backward maybe, in the sixth film.

"You're watching a mistake you made every day for 11 months—that's the way I saw it. I had the idea that Harry was like a soldier traumatized by war, and as a result of that, he shuts down emotionally. That's not a bad idea, but it's not the most interesting thing to watch for two-and-a-half hours."
