The world’s favourite storyteller turns 100 and 2016 will therefore be a rollickingly, wickedly irreverent period of irresistible madness all year long in the UK. Here’s a sampling of the surprises in store: Dahl, the spy, fighter pilot, inventor and historian of chocolate (yes, he was, too!) becomes a magical journey through The Wondercrump World of Roald Dahl at Southbank Centre (on till 3 July). Cheshire’s Tatton Park has themed Roald Dahl trails, special shows of outdoor theatre, cinema based on his works and much more (on till 2 October). The Cardiff Children’s Literature Festival (16-24 April) pays homage to him with quirky creativity (lots more at roalddahl.com/roalddahl100).
