Daniel Radcliffe: 'I hate my Harry Potter acting'

Daniel Radcliffe hated his acting in Harry Potter And The Half-Blood Prince and cringed as he watched the movie for the first time at its world premiere.

The British star landed the lead role as a schoolboy wizard in the hit franchise at the age of 11 and it catapulted him to global fame, but he is adamant some of his onscreen performances in the eight movies are terrible.

He even wished he could wriggle out of sitting through the premiere of the 2009 installment because his acting was so woeful.

Radcliffe tells British magazine Event, "Doing Potter was an incredible blessing because it gave me this opportunity to start a fantastic career. But then the moments I'm not as proud of, mistakes other actors get to make in rehearsal rooms or at drama school, are all on film for everyone to see...

"I never liked watching myself on film but I do make myself sit through it. I think it comes from not actually realising I didn't have to go to my own premieres and watch the film - that's something I've only just realised you don't have to do. I always went along and sat with everyone else watching the movie.

"It's hard to watch a film like Harry Potter and the Half-Blood Prince, because I'm just not very good in it. 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. My best film is the fifth one (Harry Potter and the Order of the Phoenix) because I can see a progression."

However, Radcliffe is adamant Harry Potter author J.K. Rowling has always been supportive of his performances as the boy wizard, adding, "To my knowledge she was always very happy with the way I played him, but it's my job to be critical."
