The Duchess of Sussex has reportedly given an interview to the team, as has Prince Harry, who was named by the monarch as Commonwealth Youth Ambassador.
Harry, and Meghan, will make the young people of the Commonwealth a priority of their public work.
Prince Charles, Prince William, Princess Anne and the Countess of Wessex have all also given interviews.
The programmes will also feature never-before-seen footage from the Queen and Duke of Edinburgh’s private film archives and treasures from the Royal Collection.
Jo Clinton-Davis, Controller of Factual at ITV, said: ‘The Queen is a unique figure on the world stage, with a huge depth of experience having met more global leaders than any previous British monarch and serving longer than all of them.
‘This film is a rare opportunity to see Her Majesty up close and behind the scenes in this role, which means so much to her and has been so significant for Britain and the Commonwealth.’ Nicolas Kent, Creative Director for Oxford Films and Executive Producer for Queen of the World, added: ‘The Queen is the most well-travelled monarch in history and it’s been fascinating to see how she has passed on her experience to the younger generations of the royal family.
‘With the Duke and Duchess of Sussex about to embark on their first Commonwealth Tour to Australia, New Zealand and the Pacific exactly sixty-five years after the Queen’s first Commonwealth Tour, this series could not be more timely.’ Harry and Meghan will tour Australia, New Zealand, Fiji and Tonga in October.'
