The Guinea Pig on AllMovie

Not a film about scientific research, The Guinea Pig (US title: The Outsider) is the story of an incipient "affirmative action" program. An impoverished young British boy wins a scholarship. As part of a sociological experiment, he becomes the first product of his "class" to be accepted in a snooty upper-crust public school. Most of the film concentrates on the effect this experiment has on the school staff. Written by actor Bernard Miles, who also plays a supporting role, The Guinea Pig stirred up controversy at the time of its release because of the presence of an alleged profanity in its dialogue. If you must know, it's the same "filthy word" Audrey Hepburn shouts at the Ascot races in My Fair Lady (64).
