This is a silly idea for two reasons. One: there has never been a good movie based on a video game. Two: I’m not a Gran Turismo expert, but as far as I know there is no story mode in any of the video games. With no existing protagonist or characters to draw from, the film is simply going to be a racing story with the Gran Turismo brand slapped on it. This *could* give the filmmakers the opportunity to make the next Grand Prix. But it will probably be the next Need for Speed.
In the year 1999, the Wachowski brothers released their sci-fi blockbuster film, The Matrix, upon the world.
In the year 2002, the Toyota Motor Corporation introduced a compact hatchback, known as the Matrix.
I THINK NOT.
