Best known for her popular rhyming stories for children, especially those illustrated by Axel Scheffler, Julia Donaldson is the multi award-winning author of some of the world's best loved children's books, most notably the modern classic The Gruffalo which has sold over 13 million copies worldwide.

Many of Julia’s books have made the journey from page to stage, and now Zog has joined them. First published in 2010, the book quickly became a bestseller, winning the Galaxy National Children’s Book of the Year Award. Then on Christmas Day 2018, Magic Light Pictures premiered an animated film of Zog on BBC One featuring an all-star cast. And now the keen but clumsy dragon roars his was onto the stage, in a new adaptation from Freckle Productions, the team behind Stick Man, Tiddler and other Terrific Tales and Tabby McTat.

Ahead of Zog flying into the Festival Theatre , Julia talks about what inspired her to write the book, and now seeing it adapted for the stage.

You’ve written almost 200 books – where do you get your ideas?

Julia: It varies, but I always develop the storyline fully in my head before I start writing. I think you read some books and you can tell that people have just made it up as they go along – but I always think, you wouldn’t start telling a joke if you didn’t know what the punchline was.

Where did the idea for Zog the dragon come from?

Julia: Well that one was quite unusual, in that the initial idea didn’t come from me. My editor said to me ‘it would be lovely to have a story about a dragon’, so I started thinking about it and the name ‘Madam Dragon’ came into my head, which I thought had a nice sound. And then I thought what could Madame Dragon do, who could she be? I came up with various ideas and a schoolteacher was one of them, so I took it from there. Originally it was going to be about a knight and a dragon, but it ended up being about a Princess and a dragon – the story came to me bit by bit.

My husband Malcolm, who is a doctor, also had some input here. Because when I was planning the story, I knew that Zog would keep meeting the Princess, and originally I was going to have them play together and toast marshmallows. And Malcolm said that’s a bit soppy, couldn’t it be something with a bit more oomph? And then I came up with the doctor angle.

The Knight, Sir Gadabout is one of my favourite comic characters because he’s such an upper-class twit. I love the line he says: ‘I’ve come to rescue Princess Pearl, I hope I’m not too late’ – when it’s actually been a whole year since she was captured.

Animals feature very strongly in many of your books – why is that?

Julia: It’s often used as a convention – like in Aesop’s Fables, where the animals aren’t really animals, they represent a quality or a characteristic. I also think it would be far more boring for the reader or listener, if Mouse in The Gruffalo was just a small but clever person, or The Gruffalo itself was a big, scary but rather stupid person. Or in The Snail and the Whale, if the Whale was just a big person and the snail a little person – I think you need animals to represent the qualities.
