Will Poulter and Lucy Boynton are set to star in Hugh Laurie's previously announced adaptation of Agatha Christie's Why Didn't They Ask Evans?.

Laurie will direct the three-part adaptation of Christie's 1934 detective novel, which has been commissioned by BritBox North America. According to Deadline, Poulter will play vicar's son Bobby Jones, who teams up with socialite friend Lady Frankie Derwent to find out what happened to a man who gasps "Why didn't they ask Evans?" on his deathbed.

Laurie will also appear on screen as Dr. James Nicholson, the Clinical Director of a nearby sanatorium. Laurie is starting shooting this week with an ensemble cast that includes Game of Thrones' Conleth Hill, I Hate Suzie's Daniel Ings, Small Axe's Jonathan Jules, and Skins' Morwenna Banks.

"I'm deeply honored to have been given the opportunity to co-lead this project with Lucy and the chance to bring Agatha Christie’s thrilling story to life under Hugh’s direction," said Poulter.

"I'm so thrilled to be working with Hugh and Will, and on this story from one of my favorite authors. I can’t wait to get started," added Boynton.

Laurie's previous directing credits include two episodes of his long-running U.S. medical drama series House and three episodes of the BBC's early noughties comedy-drama series Fortysomething.
