When I was a kid, I’d get very upset if a sports movie wasn’t realistic enough to suit me. Heaven forbid if it took dramatic license with actual events. I’m not a kid anymore, so I could appreciate all the melodrama and spectacle that director Ron Howard packs into “Rush” (2013), a based-on-a-true story Hollywoodization of 1970s Formula One racing. The rivalry between James Hunt and Niki Lauda is exaggerated. The race results are embellished. Get over it. It’s a good story with interesting characters, providing a new take on how opposites can bring out the best in each other.
