A young and relaxed Queen as she's never been seen before will be revealed in a new documentary.
The Queen Unseen uses previously unreleased footage and photos including home video style clips, to show what she is really like behind closed doors.
Photographs from her tour in New Zealand, just months after she was crowned Queen, show her relaxing by a pool with her husband, Prince Philip, and recording her own memories on a Cine camera.
In one clip, she watches on as Philip tries to get to grips with a lilo in the pool, falling off as he attempts to relax.
The footage was taken on Christmas Day when they were guests of the governor general of New Zealand and his family.
The programme comes as the Queen approaches her 95th birthday later this month.
Remembering the visit, the daughter of then-governor general Sir Willoughby Norrie, Sarah Stephenson, said: "There was one time when my sister and I were taking our dogs for a walk, the Queen saw us and said she wished she could come with us."
The Queen and Philip were with the governor-general and his family on Christmas Day, with the family giving them a stocking each on Christmas morning.
She revealed: "In the Queen's stocking there was a dog lead and in the duke's stocking there was a Wedgewood ashtray, and my father said 'the duke will be pleased because it's got his wife's head on it'. He thought it was terribly funny."
Footage by the pool also includes John Althorp, who was Diana's father. He was the Queen's equerry on the trip.
Stephenson said: "The Duke of Edinburgh is trying to get on this lilo and he has to have several attempts."
Saying that she didn't think the royal couple minded them filming, she added: "The Queen was taking similar shots. That was the Queen's smile which my mother cleverly caught. Great fun, we loved it."
The footage also shows how much the Queen relied on her husband to help her with her duties, particularly if she did find them boring.
Piers Brendon, royal historian and author, revealed her concern about how she looked when she wasn't smiling.
He said: "She felt that she had to smile all the time, she couldn't smile all the time, nobody can smile all the time.
"She said to a friend 'when I'm not smiling I look cross, I'm not cross but I look cross' and one journalist said she looked bored."
Royal historian Jane Ridley said: "Philip has come to rescue her when he has seen her looking rather bored and not taking part in the conversation, and then you can see her looking at Philip, she looks adoringly at him actually, he's her pillar, he's her rock.
"He was able to break the ice and cause a kind of thaw in the formality that surrounded the Queen."
As well as footage from the middle of her tour, there are clips of the Queen in the UK, preparing a family barbecue, and playing on the beach.
Childhood friend Lady Anne Glenconner said the Queen is "very practical" and on the beach looked "so relaxed".
One clip shows her as a child, with her sister Princess Margaret, at Royal Lodge in Windsor, before her father was even king.
It contrasts the difficulty she faced when she had to balance the Crown and her life as a mother, showing how things were different when she had her younger sons, Princes Andrew and Edward.
Ridley said: "She does things like altering her schedule of the time of her regular meeting with the Prime Minister M so she will have time to play with the babies and put them to bed
"She wouldn't have dreamt of doing at the time when she became Queen.
"She has become much more confident and her confidence in the role of Queen allows her to do these things and give priority to her children."
The Queen Unseen will also include clips of the rarely seen 1969 film Royal Family, which was withdrawn after the Queen reportedly decided she had shown too much of her family.
The film was uploaded onto YouTube earlier this year, but was taken down within a few days.
The programme will also explore how the Queen felt the pressure early on in her reign to give more of her personality away, particularly as Lord Altrincham had said she came across as a "priggish schoolgirl" and didn't show who she really was.
The Queen Unseen is on ITV at 9pm on 8 April.
