The Intruder is a 1953 British drama film directed by Guy Hamilton and starring Jack Hawkins, George Cole, Dennis Price and Michael Medwin.

Merton recognises the culprit, Ginger Edwards, as a former soldier who had fought courageously under his command in a tank regiment during the Second World War.

The story unfolds in a sequence of flash-back episodes of events during the war and how they affected, or contrasted with, how each of the main characters fared when they returned to civilian life.

The Intruder is the second film to be directed by Guy Hamilton ... it indicates an expert talent, technically very assured, if at times a trifle inclined to the showy effect.
