On Monday, McGregor teased the release with a post on Instagram:
With the tagline, "If you want it all, you have to fight for it," the film figures to track McGregor's rise to UFC superstardom after he collected $235 welfare checks in Ireland before taking his first professional fight.
Now McGregor is staring down one of the most lucrative paydays in combat sports history as he prepares for an Aug. 26 boxing match against Floyd Mayweather Jr. at T-Mobile Arena in Las Vegas.
However, the buildup to the megafight hasn't been without controversy.
Appearing at a promotional stop in Brooklyn, New York, on Thursday, McGregor was roundly criticized for his response to accusations of racism after he told Mayweather to "dance for me, boy" at earlier press conferences in Los Angeles and Toronto.
"Let me address race," he said. "A lot of people have me saying I'm against black people. That's absolutely ridiculous. Do they not know I'm half-black? I'm half-black from the belly button down."
The final stop on the press tour will be Friday at London's SSE Arena.
