And then it was time to talk about the film adaptations (and one televised adaptation, too). We were lucky enough to have Dr. Mark Aldridge, author of Agatha Christie on Screen, back on the podcast for an interview about the many films based on this novel. We hope you enjoy... and that you also forgive us the telephonic tinniness of our voices. Alas, we could not fly to England to interview Mark in person. Maybe next year?
