In their first appearance, in the 1938 Alfred Hitchcock film The Lady Vanishes, Charters and Caldicott are single minded cricket enthusiasts, whose only initial concern is to get back to England to see the last days of a Test match.

[2] Despite this, Wayne and Radford continued in the same vein, playing similar double acts in several more movies, such as Dead of Night (1945, sequence directed by Charles Crichton), A Girl in a Million (1946, Francis Searle) and Passport to Pimlico (1949, Henry Cornelius).

In the first draft of Graham Greene’s screenplay for The Third Man, two Charters and Caldicott type characters called Carter and Tombs were originally intended to be in the film.

[4] In Jonathan Coe's novel Expo 58, a pair of Foreign Office employees called Radford and Wayne appear, in a nod to Charters and Caldicott.

The BBC's 2013 telemovie of The Lady Vanishes, was based on Ethel Lina White's novel The Wheel Spins rather than a remake of Hitchcock's film, and Charters and Caldicott are absent.
