Happy Roald Dahl Day! Here are ten things you may not know about Roald Dahl's stories - from adult fiction to children's best-sellers...
Shot Down Over Libya was based on his experiences flying in the Second World War and was initially published anonymously in The Saturday Evening Post, although you can now read it in the short story collection Over To You.
In fact you could say it was The Gremlins - a story based on the gremlins of RAF folklore, and one which nearly became a Disney film.
Read Roald Dahl Museum archivist Rachel White on how The Battle of Britain helped inspire The Gremlins.
In one, Charlie Bucket visited Willy Wonka's home and fell into a chocolate mould, and in another there were ten children in the factory. What's more, it actually took several years to find a UK publisher.

...and it was he who came up with one of the scariest characters in children's literature, The Child Catcher.
The family called it "the witches' tree," and Roald used to tell his children stories about the family of foxes who lived in it.
When Wes Anderson came to create the stop-motion film adaptation of Fantastic Mr Fox, he was also inspired by Great Missenden (where the Roald Dahl Museum is now situated) with some of the pub scenes featuring Roald's old local, The Nag's Head.
In fact, the caravan Danny and his Dad live in was drawn from a real-life one that sat in the back garden and was used as a playroom by the Dahl children.

7. A number of characters appear in more than one of Roald Dahl's stories: for example, Muggle-Wump the Monkey and The Roly Poly Bird are in both The Enormous Crocodile and The Twits, with Roly Poly also appearing in Dirty Beasts, a collection of comic verse.
Many characters from Roald's short stories also appear in some of his children's fiction: Danny's Dad, William, is based on a local man who appears in the story collection Ah, Sweet Mystery of Life, whilst William and Mary - the name of a spooky adult story from the Kiss Kiss collection - were also the names of the boy's mice in The Witches.
Originally the star of a bedtime story told to Danny (the Champion of the World) by his Dad, Roald would also tell tales of this dream-catching giant to his own children. And when he came to write The BFG in 1982, he changed the original name of the character - who was initially a boy called Jody - to Sophie, after his first grandchild.
Roald quickly realised he had (in his own words) "got it wrong" and re-wrote what would become his last long children's book significantly to create the story we now know and love.

Published in 1991 - shortly after his death in November 1990 - it tells the tale of Little Billy's trip into the Forest of Sin, and of the Fearsome Beast that lives in it.
The Minpins has connections to other Roald Dahl stories: Billy is also the name of the boy in The Giraffe and the Pelly and Me, the Forest of Sin houses Vermicious Knids (who also appear in Charlie and the Great Glass Elevator) and - as Roald Dahl Museum archivist Rachel explores - there are also similarities with his first children's story, The Gremlins.
