Agatha Christie Festival

I am the Official Film Producer for the Agatha Christie Festival, working in collaboration with the Festival team.

"We have worked with John for a number of years on a wide range of film projects supporting the Festival. These have included our annual Festival film, interviews with many of our guest speakers, and several specially commissioned one-off films exploring different aspects of Agatha Christie’s life. He also created a hugely popular 1920s dance film shot along the Agatha Christie Mile.

Working with John is always a pleasure. He is professional, reliable and easy to collaborate with, and the films he produces are colourful, lively and highly creative. Together, they are building into a wonderful archive that captures the spirit and legacy of our events.

We would highly recommend Emberlense Film Productions to anyone looking for an affordable, dependable and imaginative local production company."

Official Festival Films 2022 to 2025

"Agatha Christie Festival Ltd commissioned John Tomkins and his company, Emberlense Productions, to film selected live events at the 2022 International Agatha Christie Festival to create a promotional video and trailer for future years. John responded brilliantly to our brief and delivered a superb mini-film which captures the essence of the Festival within its stunning heritage setting. We are delighted with the result."
