"Rush Hour is a 1941 British Public Information short film made by the wartime Ministry of Information and designed to pass on an important message to cinema goers in a humorous manner. Rush Hour was filmed as a series of short comedy sequences, illustrating the various degrees of chaos and confusion arising from public transport being overwhelmed with passengers at peak times. Its twin targets were employers, to whom the desirability of staggered working hours was stressed, and casual leisure travelers, who were exhorted: "Shopping? Visiting? Then get home early at your ease – leave rush-hour seats for workers, please!"
There ya go,
