If you ever face a quiz question about the most performed theatre writers in the world, likely to have a play on somewhere every day, William Shakespeare, Andrew Lloyd Webber and Agatha Christie are all reliable answers but a fourth may surprise you: Ken Ludwig. He also has intriguing connections with the other three.
The popularity that made the American wealthy enough to have donated £1m to the Shakespeare Birthplace Trust is partly due – apart from his own much-revived comedies, Lend Me a Tenor (1986) and Moon Over Buffalo (1995) – to Christie. Ludwig’s 2017 adaptation of Murder on the Orient Express has had hundreds of productions and is currently touring the UK. We meet when he is in London for a workshop on a second Hercule Poirot adaptation, Death on the Nile, which premieres in September.
