Rupert appears as journalist Malcolm Muggeridge in What a Difference, the fourth episode of this series. The New Look focusses  on the designers Christian Dior and Coco Chanel, working in Paris during and after the Second World War.

Muggeridge is played as suave and charming – but he has a complex agenda of which Chanel is unaware. Coco Chanel is portrayed by the wonderful Juliette Binoche, so at least it was a real pleasure to see her and Rupert working together!

The episode was directed by Helen Shaver, and released on 21 February 2024.
