It is revealed that Ronaldo's mother wanted to abort him after his conception and how he played through pain at the 2014 World Cup. He also talks about why he has never revealed who the mother of his son Cristiano is and about his father and brother's problems with alcoholism.
With cameras allowed into every aspect of his life, the current Ballon d'Or holder feels some may think there is too much of his life on film - but insists he simply enjoyed making the documentary.
"Too much? Maybe, but I just had fun," he said at a press conference in London, fresh from Real's first league defeat of the season on Sunday night.
"I don't regret anything. I feel unbelievable. When you do something people will find reasons to criticise you, it's normal.
"Since I was a young boy I always felt special. I saw that people looked at me with different eyes. I feel very comfortable with the cameras and media."
Ronaldo's agent Jorge Mendes reveals in the film how Valencia, Inter Milan and Barcelona all made overtures to sign the then 18-year-old from Sporting Lisbon - but wanted to leave him on loan at the Portuguese club.
He eventually signed for Manchester United. Mendes and Ronaldo say that United's manager at the time, Sir Alex Ferguson, promised he would play in at least 50 per cent of games in the first season - with the player admitting that was a big factor in convincing him that Old Trafford was the right move.
"With United I have a great passion," Ronaldo added.
"What Jorge did for me at 18 with the words of Ferguson was a dream. To play in Sporting and move was like 'wow, what is that?'
"When Ferguson wanted me and said I'd play 50 per cent of the games that was unbelievable. I took that decision because Jorge helped me. The last word from Ferguson was key also."
West Ham have been dealt a massive injury blow with the news Dimitri Payet could be ruled out for three months.
The Frenchman has been a major factor in the Hammers' fine start to the season following his £10.7m move from Marseille.
