Whodunnit? was a British television game show that originally aired on ITV.
Each week it featured a short murder-mystery drama enacted in front of a panel of celebrity guests who then had to establish who the murderer was. The panel members could interview the remaining characters, with only clue being that only the murderer could lie. Each panelist could also request to see a short replay of one section of the initial drama, which would often include events as they occurred and flashbacks as seen and narrated by individual suspects.
