Sir Michael Gambon has revealed that he does not read the Harry Potter novels, according to reports.

The actor, 68, has played Professor Albus Dumbledore in the wizard franchise since third instalment Harry Potter And The Prisoner Of Azkaban, after taking over the role from the late Richard Harris.

However, Gambon said that he will never pick up one of J.K. Rowling's books for fear of spoiling the illusion of working on the films.

Contactmusic quotes him as saying: "There's no point reading the books because you're playing with the screenwriter's words. Besides, you'd get upset about all the scenes the script is missing from the book, wouldn't you?"

The star recently revealed that he will feature in final picture Harry Potter And The Deathly Hallows, which will be released in two parts.

Latest movie Harry Potter And The Half-Blood Prince is in cinemas now.
