Daniel Radcliffe completely regrets his performance in Harry Potter and the Half-Blood Prince

With eight movies to choose from, you'd probably expect the Harry Potter stars to favour some scenes over others, but Daniel Radcliffe has revealed there's one whole instalment in which he regrets basically everything he did.

The actor was just 12 years old when he first donned Harry's recognisable glasses and heard Hagrid tell him he was a wizard, so you couldn't blame him if his performance was a little lacking in experience.

Obviously, though, the first instalment of the Harry Potter movies proved successful enough to warrant six more films after that, so it's fair to say he was doing a decent job.

But like all of us, Radcliffe has looked back on his life with wishes that he could do some things differently - specifically, his entire performance in Harry Potter and the Half-Blood Prince.

The sixth instalment in the series, the film was released in 2009 and saw Harry discover an old potions textbook belonging to a person calling himself the Half-Blood Prince, which he managed to put to use when he was actually in class, and not fighting off a determined and power-hungry wizard with no nose.

In a 2015 interview with Playboy, Radcliffe revealed that his performance in the film was the one he was least proud of, explaining: "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."

Radcliffe said he 'really enjoyed' his performance in the fifth film, noting that 'part of it was how much [he] worked with people like Gary Oldman (Sirius Black) and David Thewlis (Remus Lupin)', but continued: "On the sixth, I remember watching it and thinking, Wow, there’s been no growth.

"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 traumatised 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."

Though Radcliffe believes his performance wasn't that exciting, he described his time on set as being exactly the opposite, dubbing it 'the best place on Earth'.

"I loved it from the word go," he said. "I loved being on set. I loved the hours. I loved the people. I loved the crazy, weird sh*t I got to do every day. Acting was the focus for me, and I wasn’t going to do anything to jeopardise being an actor."

After wrapping up Harry Potter in 2011, Radcliffe has gone on to appear in The Woman In Black, Now You See Me 2 and most recently, Weird: The Al Yankovic Story.
