Senna - Really great documentary about the beloved Brazilian racer Ayrton Senna. This is a great film by itself, I can't recommend it enough.
Rush - A pretty decent movie. It's definitely entertaining and holds your attention. The ad campaign was terrible. I didn't know what it was about until after a few friends told me to see it.
1 - Possibly the worst title for a movie. Good luck trying to find this one online. Forgetting the name, it's a good documentary if you're into Formula One. It's about how engineering and safety evolved in the sport. The pacing is slow, feels like something from PBS. If you watch Senna and Rush then you may want to see this.
