It is based on the true story of Jann Mardenborough, who would become a real life race driver after winning a series of gaming tournaments for the game series which the movie is titled after.
Mardenborough got his start through GT Academy, a UK television series using the game series as a launchpad for young hopeful drivers attempting to break into real racing.
After winning the contest, he would go on to the F3 and GP3 series and would even race in the prestigious 24 Hrs of Le Mans.
The movie is expected to air relatively soon, with a release date set for August 2023, less than a year from now. Of course dates are always subject to change, so it will remain to be seen if they stay firm on that launch date.
Most recently for the franchise, Gran Turismo 7, launched earlier this year and is available on PlayStation 4 and PlayStation 5. You can check out our review for it here.
