I seem to be going through a period of watching sporting documentaries.
A few weeks ago I saw Closer to the Edge, a 3D movie about the Isle of Man TT, at the cinema. It was an exciting film but I had a few journalistic issues with it.
And then, on Saturday, we went to see Senna, a documentary about the life and death of Formula One racing driver Ayrton Senna, which left me reeling in its wake. I came out of the cinema feeling completely shell-shocked, and I've been thinking about the film ever since.
I think it's fair to say that Senna is a triumph of film editing. There are no "talking heads" in the film. The entire feature has been put together using archived footage of interviews with Senna, including race footage and home movies.
Similarly, there is no single person narrating the story. It is told by sound clips and interviews with people close to Senna -- his mother, his sister -- and those that worked or raced alongside him, including key figures in Formula One racing.
It all adds up to a well-rounded portrait of a young Brazilian who is regarded as one of motor racing's greats.
Even if you don't like F1, I'd urge you to go see this film. Not only is it a a truly remarkable feat of documentary film-making, it tells a compelling story about a man who transcended sport to become a global superstar without losing his integrity, his values and his beliefs.
Obviously it doesn't have a happy ending -- Senna was killed at the San Marino Grand Prix on May 1, 1994 -- but the film is inspiring, dramatic and sobering, by turn. I hope it garners awards aplenty for the director Asif Kapadia.
