British character actor and comedian, 1911-1990. Became popular in the 1950s in films such as Private's Progress, School for Scoundrels, Those Magnificent Men in their Flying Machines and Carlton-Browne of the F.O.. He contracted Parkinson's Disease in 1971, and died, poor, in 1990.

Throughout the 1960s he was ubiquitous, appearing in 37 films; after which he became quite obscure and largely forgotten. He usually played an exaggerated upper-class scoundrel (sometimes even a rapscallion), and his catchphrase was 'X is an absolute shower' (with the last word pronounced 'shaaaar').

Dick Dastardly from the Wacky Races is loosely based on Terry-Thomas, whose real name was Thomas Terry Stevens.

Nowadays he has a cult reputation.
