In the opening shots of the Savoy Hotel, numerous national flags are shown flying above the entrance. The Canadian Red Maple Leaf flag is clearly visible. Unfortunately, the time setting of the film predates the adoption of the Canadian flag in 1965. This time setting is borne out by a reference by one of the characters as claiming to be the son of a very important and busy man, Winston Churchill. Churchill died in February of 1965 and the Canadian flag was adopted later that same year. So if Churchill was alive and, a busy and important man, the Flag of Canada would have been a red ensign bearing the Canadian Shield not the red Maple Leaf Flag.
