The Great St. Trinian's Train Robbery is a British film comedy set in the fictional St Trinian's School, released in 1966, three years after the Great Train Robbery had taken place. It also parodies the technocratic ideas of the Harold Wilson government and its support of the comprehensive school system.
Directed by Frank Launder and Sidney Gilliat with a script by Sidney and Leslie Gilliat, it was the fourth in a series of five St Trinian's films, and the first of them to be made in colour. It retained George Cole, Richard Wattis, Eric Barker, Michael Ripper and Raymond Huntley from the earlier films. Several new actors were brought in, including Frankie Howerd as Alfred (Alphonse) Askett, Reg Varney as Gilbert, Dora Bryan as headmistress Amber Spottiswood, and Stratford Johns as the Voice.
Although asked twice, Joyce Grenfell refused to appear again as Sergeant Ruby Gates; she was later reported to have said that she regretted appearing in the St Trinian's saga. Raymond Huntley appeared as the "Minister of Schools" (a fictional title), having appeared in a different role in the earlier films; and Cyril Chamberlain appeared as Maxie.
The extensive use of trick gadgets in Alphonse's hairdressing salon (used to communicate with the gang's mastermind) spoofs the secret gadgets used in the James Bond spy films of the Sixties, while the gimmick of having the mastermind conceal his identity throughout the film (he is never seen on screen) spoofs the character of Bond villain Ernst Stavro Blofeld, who was originally only an unseen voice.
