This trailer is very important for marketing the film "Senna". While Formula 1 fans would probably already know about this film and be planning on seeing it (like me), non-F1 fans would need to be persuaded. This trailer does that by focusing a lot on the person as well as the racing (like the film, actually). Also, the trailer manages to quickly tell (the main parts of) the story of Ayrton Senna to everyone, even people who do not know anything about F1. By adding extra things, like some of the controversies, accidents and successes from Senna's career and life, the trailer gives viewers more reason to see the film than they probably had before they viewed this trailer.
