Postman's Knock

Promoted to a new position in a “big city” London post office, unassuming mail carrier Harold Petts (Spike Milligan) makes a splash on his first day when his arrival inadvertently foils a mail train robbery in this classic comedy. When he immediately gains recognition for his mail-sorting prowess, Harold catches the eye of the police, who assume that the amiable postman is plotting to rob his new place of employment.
