It Happened Here

It Happened Here (also known as It Happened Here: The Story of Hitler's England) is a 1964 British black-and-white war film written, produced and directed by Kevin Brownlow and Andrew Mollo, who began work on the film as teenagers. The film's largely amateur and independent production took some eight years, using volunteer actors with some support from professional filmmakers.

It Happened Here shows an alternative history in which the United Kingdom has been invaded and occupied by Nazi Germany during World War II. The plot follows the experiences of an Irish nurse working in England, who encounters people who believe collaboration with the invaders is for the best, while others are involved in the resistance movement against the occupiers and their local collaborators. The film's title is an allusion to Sinclair Lewis's 1935 novel It Can't Happen Here.
