Documentary Show Lighthearted Queen Elizabeth

Wearing a floral dress and no hat, Queen Elizabeth strolls in dappled sunlight through the garden at Buckingham Palace with an old acquaintance, making quips and even mentioning the prospect of her own demise in a light-hearted way. The scene, filmed last summer for a documentary due to be broadcast in Britain next week, offers an unusually informal glimpse of the 91-year-old monarch, who has given very little away of her inner self during her 66-year reign.
