Recalling the first time he saw the movie, an unedited version, he said the Sushant Singh Rajput starrer gave him an oppurtunity to relive his past as memories of his childhood, where he lived and how he played flooded his mind.
"All those things that had happened became fresh in my memory --- from where I lived, how my school was, where we played. I went blank," said Dhoni, who normally does not show much emotions on the field.
In the United States along with wife Sakshi and producer Arun Pandey (whose firm manages Dhoni) to promote his film, which is due to release worldwide on September 30, Dhoni spoke about his life and the transformation from a talented small town boy to one of India's most respected captain.
"One thing I told Pandey (director Neeraj) is that this movie should not be to glorify me. It's about the journey of a professional sportsperson and that's what it should depict," Dhoni told reporters here during film's promotional event.
Being a person who likes to live in the present, it was "difficult" for him to go back into his life and narrate history to Pandey for the movie.
When asked if he was worried about how the world will perceive him as a human being and cricketer after seeing the movie, he replied in the negative.
"I was a little worried when initially the concept of the movie came but once we were in, I was not worried about it as I was just narrating my side of the story," he said.
Dhoni also shared moments from his cricketing life that had a huge impact on him.
He said the World Cup loss of 2007 and the ensuing reactions against him and the team had a big impact on him and to some extent that experience "was a big turning point in my life".
He said in India when a team loses a cricket match, they are perceived as people who "have committed a crime or are murderers or terrorists."
He recalled the harrowing time when the team had returned home after making an exit in the first round of the 2007 edition. People pelted stones at Dhoni's residence.
Dhoni admitted that his captaincy is more about gut feeling as it comes from the experiences of his life.
"Gut feeling is all about the experiences that you have had in your life. It is about being in difficult scenarios, knowing what worked, what did not work and then taking a decision."
