Dumbledore hasn’t read a Harry Potter book
The Harry Potter books haven't cast a spell over Sir Michael Gambon - he has never read them.
The actor plays Dumbledore in the hugely popular films. But he said he refuses to read books that his films are based on in case he's disappointed with scenes that are left out of the script.
He said, "I've been in five Harry Potter films and never read a Harry potter book.
"If you are an actor all you have is the script. If you read the book you might get disappointed about what's left out."
Gambon is currently filming a lavish BBC adaptation of Jane Austen classic Emma - and true to form, he insists he has never read the novel.
