Overview
Paper Tiger is a 1975 British drama-adventure film starring David Niven and the child actor Kazuhito Ando, who later portrayed Teru Tendou in Ganbaron. The film was based on a novel of the same name by Jack Davies, who also wrote the screenplay.
The title comes from a Chinese expression meaning a person who looks powerful or strong but is in fact ineffectual.
Plot summary
Walter Bradbury (David Niven) is an apparently well-educated, decorated ex-military Englishman. He informs strangers he is the son of a viscount, a Member of Parliament, and a nephew of a general, and walks with a limp and cane which he says is due to crashing in the Le Mans 24-hour race.
A Japanese ambassador to a fictional Asian country ("Kulagong") is attracted to Bradbury's claims of receiving the Military Cross (MC) twice and the Croix de Guerre once during the Second World War and hires Bradbury to tutor to his son, Koichi (played by Kazuhito Ando).
