Prince Charles is sharing some of the royal family's home movies in a documentary paying tribute to his mother, Queen Elizabeth II, as she marks 60 years on the British throne.
The program includes shots of a 9-year-old Charles and his younger sister Princess Anne buried up to their necks in sand during a beach holiday in 1957 _ with a corgi, the queen's favorite breed of dog, between them.
The documentary will be screened on BBC television Friday.
Britain is marking the queen's Diamond Jubilee with a series of events including a 1,000-boat pageant along the River Thames on Sunday and a service of Thanksgiving on Tuesday.
In the program, the prince praises "Mama" for providing "continuity in a time of immense change over 60 years."
