"I'm the type of person, I get nervous before my first race," Bolt says.
"Every year I worry, am I still fast?
"This year I've said, I'm having doubts, I'm not motivated ..."
Yet promoters have remained tight lipped over what material will be used in the documentary, which is released worldwide on November 28.
While the film says audiences will be treated to "a unique insight into the life of a living Olympic and sporting legend, best friend, teammate", what is apparently lacking is the inclusion of his controversial relationship with long-time girlfriend Kasi Bennett, and those infamous infidelity reports.
Remember those? Where he celebrated his 30th birthday by making out with a brunette, twerking with another and then vaulting into bed with a third - who posted racy images of their tryst online.
Undoubtedly, the sordid story and the couple's guidelines on monogamy is what the public really, really wants.
In August, news.com.au reported that just days after the sprint king's sister declared his long-term girlfriend Kasi Bennett would be perfectly suited to marry him, the nine-time Olympic gold medallist was caught thrusting his heart out on the backside of a woman inside a Rio club.
Bolt was reportedly pictured the next morning in bed with another woman - not the young lady featured in the above videos.
The Daily Mail reported 20-year-old Rio student and mum-of-two Jady Duarte shared photos of herself in bed with Bolt the morning after.
He was then pictured kissing and licking women at Rio nightclubs before flying to London, where he went out at West End clubs on Monday, Tuesday and Wednesday nights,The Sun reported.
Multiple women were seen heading back to his central London hotel in taxis.
"I'm sure Kasi will be used to it by now. She is used to seeing pictures like this," Christine Bolt-Hylton, the superstar's sister, told theDaily Mail.
"The pictures are of a young girl. I know she will be upset. But she will talk to him and I know they can work their difficulties out.
"Usain doesn't believe in cheating. ... He has never done this before as far as I know," she added. "When he was much younger he was popular with the girls but from when they have been together, he hasn't done anything like that."
In fact Ms Bennett is nowhere to be seen in the documentary's bio, despite "in-depth interviews with those closest to him - his parents, best friends, agent, coach and fellow athletes" credited in the mix.
Bolt's sister added Kasi "was definitely OK" over the images, with proof coming in the form of an apparent engagement a week later.
"My aim with making this film is to show people how my life really is ... What I've been through to get me where I am today, the ups and the downs, and an insight into what I am thinking and feeling," Bolt claimed.
"I know a lot of people around the world feel like they know me already but I'm excited for everyone to see the real me in I Am Bolt."
Whether audiences will see the "real me" is yet to be seen.
