The Greengage Summer (called The Loss of Innocence in the U.S.) is a 1961 British drama film directed by Lewis Gilbert and starring Kenneth More and Susannah York (in her first leading role). It was based on the novel The Greengage Summer (1958) by Rumer Godden. Set in Épernay, in the Champagne region of France, it is the story of the transition of a teenage girl into womanhood. More later named it as his favourite film, stating, "[Susannah York] was just twenty-one and an adorable creature...it was one of the happiest films on which I have ever worked."
