No, this isn't a trailer for a new Gran Turismo video game. There is a major connection to the popular racing franchise, however. In 2008, Nissan and Sony teamed up to create the Nissan GT Academy where gamers could compete in the sim racing world for a chance to join Nissan's real-life race team. Gran Turismo tells the story of Jann Mardenborough, one of the winners in the series.
As such, the trailer features all kinds of automotive action in both the sim world and real world. Mardenborough (played by actor Archie Madekwe) is a young man who's an ace at Gran Turismo and joins the GT Academy, apparently to the dismay of his father (played by Djimon Hounsou in the film). It also seems David Harbour's character Jack Salter isn't pleased about the idea of giving sim racers a seat in real cars, as he tells Danny Moore (played by Orlando Bloom) "It will tear them to pieces." At this point, it's worth noting that the movie is based on a true story, but isn't a documentary by any means.
