The Great St. Trinian's Train Robbery is a British comedy film, directed by Frank Launder and Sidney Gilliat, written by Sidney and Leslie Gilliat, and released on 4 April 1966. It is the last of the original series of films based on the St Trinian's School set of images and comics, and the only one to be produced in colour. The film stars a selection of actors from previous films in the series, including George Cole, Richard Wattis, Eric Barker, Michael Ripper, and Raymond Huntley, alongside Frankie Howerd, Reg Varney, Dora Bryan, and the voice of Stratford Johns. The film's story focuses on St Trinian's becoming caught up in a train robbery, after the gang who conducted it attempts to reclaim their loot from the building that the students and teachers now inhabit. The story itself is based on the actual Great Train Robbery that took place in 1963, and includes numerous parodies of the technocratic ideas of the Harold Wilson government and its support of the comprehensive school system, and spoof elements based upon those from the James Bond spy films of the Sixties. Plot Gang leader "Alphonse" Askett, who operates under the guise of a hairdresser, is contacted by his anonymous employer, a secret mastermind, on a plan for a major train robbery. The gang are instructed to rob a mail van of £2.5 million, and hide the loot at Hamingwell Grange, a deserted country mansion, until it is safe to reclaim it. Meanwhile, Amber Spottiswood, the headmistress of St Trinian's, has an affair with Sir Horace, the new head of the Ministry of Schools (a fictional government department) and a corrupt politician, who recently took over following a Labour Party election triumph. Much to his department staff's shock, he willingly provides the school a grant in order to relocate following a fire at their previous building. St Trinian's moves into Hamingwell as a result, which subsequently spook Askett's gang when they attempt to return to recover their loot. Learning of what happened, the gang's mastermind instructs Askett to find a means to retrieve the stolen money without raising suspicions from the school. Askett decides on sending his delinquent daughters into St Trinian's as new pupils, instructing the pair to gather any useful information that the gang can make use of. Unknown to Askett, one of the students at St Trinian's comes across some of the stolen money
