You would hope that a documentary about a motorcycle race shot in 3D would be an exciting watch, packed with suspense, making the most of 3D technology to subtly draw you into the action. TT3D: Closer To The Edge is certainly that, but what you might not anticipate is quite how funny and moving it also turns out to be.
You also need absolutely no knowledge of, and barely any interest in, motorcycles. In the same way that you don't have to be a Black nationalist, porn star or White supremacist to enjoy Louis Theroux's documentaries about those subcultures, you don't have to be a petrolhead to appreciate the incredible characters showcased here, or to find the climactic race sequences utterly compelling.
Race star Guy Martin in this film's main focus, and he's an ideal subject for any documentarian. Charismatic and very much marching to the beat of his own drum, he's also very childlike. Prone to sulks but also an eternal optimist, his idiomatic speech and lack of guile stand in welcome contrast to the more guarded, media-trained stars of better known sports.
Where the film excels is in letting the drivers and the drama of the track tell its own story. What little narration there is is provided by Jared Leto, but truth be told it's barely needed, and it's massively refreshing to watch a documentary without a Louix Theroux, Werner Herzog or Morgan Spurlock author/presenter firmly thrust to the fore.
