The past is coming to life in madcap and anarchic style with the return of Horrible Histories to Norwich Theatre Royal.

The Terrible Tudors and Awful Egyptians are promising thrills, laughs and some stunning 3D effects from May 23 to 25.

Terry Deary is the man behind the hugely-successful books which inspire the show and reveals the facts which were too horrible to include in his books and his plans for the future.

When you wrote your first Horrible Histories, did you ever imagine the idea would go on to be so successful?

Yes, I think most authors believe their work will be a huge success even though most books disappear from print after a couple of months.

It's that hope that keeps us going.

When I wrote my very first fiction book 38 years ago, my publisher said, 'writing is like a sausage machine and you have to keep stuffing in at one end so something comes out the other end. It is like a process'.

I kept writing book after book – fifty fiction titles before Horrible Histories came along - but I never imagined I would have a series which would become first of all iconic and secondly that would still be selling 25 years later.

Roald Dahl has managed that, but I can't think of anyone else who is still selling so well.

What usually happens is that people have sensational ideas and they sell really well for a while but they do tend to come and go. It is a shame you can't predict which ones will last.

What do you believe is behind the popularity of Horrible Histories?

Nobody had done anything like them before and they filled a desperate need.

There were fact books for children but they tended to be written by experts on the subject.

They knew their history but they didn't have a clue how to write about it for children.

So with Horrible Histories, instead of an expert who couldn't write, they approached a children's author who knew nothing about history.

I get all my facts from research.

I do my research and say 'you will never guess what I discovered' and 'phwoar, this is great'.

It is actually a simple answer. I say I am not an expert in history and this is why they work.

Down the years people have tried to copy Horrible Histories by doing funny fact books but they never get it right because they use experts, not writers.

Have you ever found any facts which were too horrible to include?

Well the publishers have said so.

For example when the Vikings invaded they became settlers and had families here but these settlers were as vicious as the Vikings.

On the other hand there are facts which some people feel you can't talk about, say in World War Two.

For example when we came to the television series, we were sitting round the table and we talked all about the bombings and the blackout and got that sorted.

Then we got to the Holocaust and there were six or seven pages and they read them in silence and then said 'of course we can't do that'.

I am actually quite proud of the fact that television can't do the Holocaust but I can.

When I went to school it was all about the Romans.

It was the Romans who brought civilisation, the Romans who gave us water supplies and aqueducts, the Romans who brought us straight roads.

That is what they told us all the time but the Romans were also the most evil people there were.

They are the only people who killed people for sport.

Thousands of them would go to an arena and watch people killed for sport and they are held up as models of civilisation.

And, because teachers are telling them that, children grow up thinking the Romans were really civilised. Horrible Histories tell the truths that, in the past, teachers have cut out from history.

Why does Horrible Histories work so well on stage?

We work really well as a team.

Neal Foster, the director of Birmingham Stage Company which presents the show, is very knowledgeable and experienced in children's theatre. Birmingham Stage Company has been going for 25 years now and I have been a professional actor for 40 years so, between us, we know what we are doing. We are not trying to write literary stuff. It isn't the books on stage.

We are not determined to be true to the spirit of the books because we are writing for theatre so it is fresh and original.

So what is next for you?

I have now created adult history books in a new series called Dangerous Days.

The first was entitled Dangerous Days in the Roman Empire followed two years ago by books on Victorian Railways, Elizabeth I and Ancient Egypt.

They have a layer of humour and are a bit gruesome.

They are more or less Horrible Histories for adults but we can never ever use that title.

There will also be new Horrible Histories titles while I'm also planning movies and television series based on my adult books and my fiction.

After all this research, are you now an accidental history expert?

Definitely not. I know very little about history because I can't keep it all in my brain.

I have only got about three brain cells.

I often forget what I have written because I can't hold all those facts.

I pick up a Horrible Histories book, maybe to revise it, and I read something and think 'I never knew that.'

I can be an anorak with facts though.

I was watching Horrible Histories on television and up came the Vile Victorians and along came Burke and Hare, the body snatchers.

I was jumping up and down and shouting at the television 'no, they were 1827 – 12 years before Victoria came to the throne. They weren't Vile Victorians!' Now that is an anorak.
