YMMV / Whodunnit? (UK)

• Retroactive Recognition: Although the performers in the short films often included familiar faces from the British stage and screen (such as Edward Sinclair, Frank Thornton, Burt Kwouk, and Kate O'Mara), some of the cast members' most famous roles were still years ahead of them:
  • The voice of photography studio investor Ralph Damon from "Portrait in Black" may be more recognisable to modern viewers than his face, as his actor, Gerald Flood, provided the voice of Kamelion in the Peter Davison era of Doctor Who several years later. Meanwhile, his fellow suspect, hairdresser Ray Hunt, is played by a young David Yip, six years before his breakthrough role in The Chinese Detective (and nine years before his single scene as Wu Han in Indiana Jones and the Temple of Doom).
  • Dave the drummer in "Pop Goes the Weasel" was played by a young Robert Lindsay, who had only just been cast as Jakey Smith in Get Some In! and was still a few years from finding greater fame in such series as Citizen Smith, G.B.H., and My Family.
  • Mary Tamm appeared as suspect Valerie Austin in "Nothing to Declare" several years before being cast in her most famous role as the first Romana in the Tom Baker era of Doctor Who.
  • Malcolm Jackson, son of the Victim of the Week in "Death at the Top", was played by Christopher Biggins when he was still mostly known as a character actor (his previous roles included Lukewarm in Porridge); his performance as Nero in I, Claudius, just the first of many roles that brought him to a wider audience, was still a year away.
  • Commander Blade of MI5 in "Too Many Cooks" was played by Clive Swift over fifteen years before he found more enduring fame as Henpecked Husband Richard Bucket in Keeping Up Appearances, while suspect Clarence Brooks was played by Edward Hardwicke over a decade before he played Watson to Jeremy Brett's Holmes in ITV's Sherlock Holmes adaptations. And sharp-eyed viewers may notice a 17-year-old Peter Capaldi in the front row of the studio audience, just behind the members of the public playing along with the celebrities.
  • Arthur Johnson, son of the Victim of the Week in "Worth Dying for", was played by a young Jeff Rawle, whom contemporary audiences are more likely to recognise as George from Drop the Dead Donkey or Amos Diggory from Harry Potter and the Goblet of Fire.
  • DI March in "Time to Dye" and Philby in "A Dead Cert" were both played by Paul Darrow, who was still a few years away from being cast as Avon in Blake's 7.
  • Sergeant Channing from "Final Drive" is played by Gary Waldhorn, who would later be best known for playing David Horton in The Vicar of Dibley.
  • General Malkol from "A Deadly Tan" is played by John Bluthal, who would later be best known for playing Frank Pickle in The Vicar of Dibley.
  • Private Rhodes from "Goodbye Sarge" is played by John Challis, who would later be best known for playing Boycie in Only Fools and Horses and The Green Green Grass.
  • Miss Frisby from "No Happy Returns" is played by Josephine Tewson, who would later be best known for playing Elizabeth Warden in Keeping Up Appearances.
  • Jackie Meredith from "Underneath the Archers" is played by Moira Foot, who would later be best known for playing Denise Laroque in 'Allo 'Allo!.
  • Roy Sharp from "Beware, Wet Paint" is played by Norman Eshley, who would later be best known for playing Jeffrey Fourmile in George & Mildred.
  • Mr. Bailey from "Worth Dying For" is played by Robin Parkinson, who would later be best known for playing the third LeClerc in 'Allo 'Allo!.
  • Miss Tillitson from "No Happy Returns" and "Last Tango in Tooting" is played by Vivienne Johnson, who would later be best known for playing Young Mr. Grace's Nurse in Are You Being Served?.
