Jim Broadbent has revealed he isn't a fan of Harry Potter.

The 58-year-old, who will appear in the upcoming Harry Potter and the Half-Blood Prince, said he's only read two of the series's seven books.

"I'm not a massive fan, no, it's not really part of my generation. I had read the first one and seen the films. I caught up with the sixth one, which I'm in, but I have to admit I haven't read them all."

Describing the experience of working on the big budget Warner Bros film, Broadbent added: "It's going great. I play Horace Slughorn. He's a retired teacher brought out of retirement and drawn back into Hogwarts to tell his tale. He's got a secret that they want to get out of him."

Brit actor Broadbent won an Oscar in 2002 for his portrayal of John Bayley in Iris.
