Looking magnificent in his beautifully fitted suit, he charmed the audience instantly, with his wit and charisma. He had the entire room eating out of his hand! He was very aware that although his books are written for children, the adults were craving his attention too. There were several jokes that were aimed at the older members of the audience, to which David muttered, ''that reference was for the adults.''
He read from both ''Awful Auntie,'' and ''Gansta Granny.'' He voiced the characters individually, having the children in hysterics. He was honest and open when asked questions. Here are some of the hi lights of his interview and questions from the children. Be aware, I did this from memory, so it may not be one hundred percent word for word!
Question: What's your favourite book that you've written?
Answer: Harry Potter and the Philosophers Stone (laughter), I let that JK Rowling person take the credit for it, but it was really me!
Question: Have you met the queen?
Answer: Yes, a few times, she's a lovely lady. I always feel a little awkward, because you are not allowed to ask her questions. When I hosted ''The Royal Variety Show'' in the UK, I met her after, I felt so silly because I said, ''thanks for coming.'' (The ROYAL variety performance is a show attended by the Queen, ALWAYS!)
Question: How do you come up with your villains?
Answers: One of my villains originated from a contestant we had on Britain's Got Talent. He was eating live cockroaches on stage. I thought to myself, if he eats cockroaches, what else is he capable of? Would he make burgers from rats? Then and there, my villain for ''Ratburger'' was born.
Question: What does Simon Cowell think of your books?
Answer: Well, when his son Eric was born, I wrote a book especially for him and had it illustrated. Simon said that it could have been better, but I think he was joking. I think he was secretly touched.
Question: Do you have an awful auntie?
Answer: I have three aunties, but to say they are awful would be unkind. I do base my characters on people I meet, but she is not based on any of my own aunties.
Question: Did you swim here?
Answer: I didn't, it's too cold. I did swim the channel though. (Much laughter from David and the audience).
Question: You have a lot of famous people in your movies (adaptations of the books), did you have people in mind when you wrote them?
Answer: For some of them I did. Unfortunately some of the Hollywood superstars were not available! (Laughs) We had Kate Moss in ''The Boy in the Dress.'' this was amazing since she doesn't usually agree to do anything like this. It was a rare occurrence.
Question: Maybe you could get Peter Jackson involved with your next movie?
Answer: No way, it would probably be 27 hours long!
Question: Which author inspired you?
Answer: Roald Dahl and Dr. Seuss. I remember going to library as a child, I chose ''Charlie and the Chocolate Factory,'' because I like chocolate. Roald Dahl's books got me reading and I still read those books today.
My father used to read Dr. Seuss to me, they were also amazing books. All of this inspired me to write something for the same age group.
Question: Who is your favourite author?
Answer: Kazuo Ishiguro. A great writer.
Question: What are you reading now?
Answer: I just finished a fantastic book, ''H is for Hawk,'' by Helen Macdonald (another wonderful guest of the festival). If you haven't read it you should. It's beautifully written.
Mr Walliams stayed behind to sign books for nearly three hours! He signed every single book, allowed everyone a question, AND posed with every child for a photo. This is a person that cares very much about children and genuinely wants to be around the fans of his work. Thanks for dropping in on New Zealand David. Huge thanks to the 'Auckland Writer's Festival' for bringing David over. New Zealand is quite in love with him!
