Invasion of the Giant Pythons

Queen and Country
Royal Visit
Airs Sunday, July 8 at 7:00 PM
The Queen’s year is driven by her diary — and has been since her accession in 1952. See her in Scotland at the Braemar Gathering (which she has attended 70 times) and follow her on a visit to Liverpool – the sort of regional trip that happens every week but attracts little publicity. View unique 3D footage of the young queen, shot in 1953 and held by the British Film Institute.
