The third collaboration between director Joseph Losey and writer Harold Pinter, following The Servant and Accident, continues their exploration of class rituals and the darker recesses of desire.
Pinter's script adapts the 1953 L.P. Hartley novel about Leo Colston, a middle-aged man (Michael Redgrave), recalling a summer of his early adolescence at a country estate. Young Leo (Dominic Guard) observes the machinations of the adults in the household, all but two of whom conveniently ignore his presence.
Marion Maudsley (Julie Christie) is promised in marriage to another aristocrat, but she is secretly in love with farm worker Ted Burgess (Alan Bates). They enlist Leo as their messenger, with tragic consequences for all concerned.
The older Leo has never married, and as the story winds on, it becomes clear that his own infatuation with Marion irrevocably altered his life. The Go-Between won several British Academy Awards, including one for Pinter's screenplay, and was one of four films awarded a grand prize at the 1971 Cannes Film Festival.
