Trying to integrate the movie with the real sport and real drivers is just a horrrible idea, definitely smells like a move to promote F1 as a sport. They should've trained or CGI'd more actors to play other drivers. Heck, it would even be cool if they resembled some real drivers so that F1 fans could have a guessing game who's that on the screen.
The first trailer simply sucked with most of the shots featuring the team from the movie fighting "solo".
