The duo appeared in two films, Mon petit doigt m'a dit.

Adapted by Pascal Thomas, the names were altered, Tuppence reverting to her full name, Prudence, and Tommy changing to Bélisaire. It wasn't until 2005 that another screen version of the couple would appear, this time in France. They appeared again in 1985 with the LWT full length television film of The Secret Adversary. The two actors made a convincing couple and the lavish sets and costumes from the 1920s made this a popular series. It featured ten of the fifteen short stories from the book of the same name. In 1984, the Partners in Crime television series aired on London Weekend Television, starring James Warwick and Francesca Annis as Tommy and Tuppence. They were played by Richard Attenborough and his real-life wife, Sheila Sim, and took advantage of their (then current) starring roles on stage in The Mousetrap. It wasn't until 1953 that the couple appeared in an English adaptation, this time on BBC Radio in a series of half-hour episodes adapted from the collection Partners in Crime. The Secret Adversary was the first Christie feature film ever made adapted by the Fox Film Corporation in 1928 as a silent movie for Germany titled 'Die Abenteuer G.m.b.H', which translates as ‘Adventures inc’. Their adventures take them through four novels and a short story collection, marrying at the end of the first book, The Secret Adversary, and going on to have three children: twins Derek and Deborah, and an adopted daughter called Betty. Their stories were the ones Agatha Christie enjoyed writing the most she took real pleasure from her bright young things, and they are the only detectives in Agatha Christie’s arsenal to age with each story, keeping approximate pace with Christie herself. Christie describes Tommy’s face as “pleasantly ugly – nondescript, yet unmistakably the face of a gentleman”. Tuppence often leads the way with her impetuous, charismatic nature, while Tommy’s slow, considered manner provides the perfect foil.

It’s just after WW1 and jobs are very thin on the ground so Tuppence comes up with a plan to form 'Young Adventurers Ltd' - 'Willing to do anything. Young Tuppence Cowley bumps into old friend Tommy Beresford at Dover Street tube station. The first Tommy and Tuppence adventure was published in 1922.
