This film is not, as the title might suggest, a feature length adaptation of 'Top Gear'. It's a biographical drama, telling the real-life story of the upstart Ford motor racing team attempting to challenge the dominance of Ferrari in the world of Le Mans endurance racing during the 1960s.
The producers were presumably inspired by the success of 2014's 'Rush' at the box office, which was also a biography from the motor racing world. Both Christian Bale and Matt Damon are in leading roles, which is as close as you'll get to a guarantee of quality; no matter what's in the script, the two performers will make you care about it. We won't spoil it for you, but we can say that the true events the film is based on are inspiring and exciting, so as long as the film does the story justice it should be excellent.
