Here is a skateboarding documentary with a meaty story to tell – though sometimes it strays suspiciously far from objectivity. It is the extraordinary and tragic tale of the Pappas brothers, Tas and Ben, two teenagers from suburban white Australia who travelled to the US in the 1990s with the purpose of conquering the vertical skateboard scene. And conquer it they did, for a while, before succumbing to drugs and wild times and finding themselves repeatedly frozen out as Aussie outsiders by the world of corporate-sponsored skateboard competition, whose judges appeared to favour the homegrown American star, Tony Hawk. (In boxing, they say it's the kind of place where you have to knock their guy out to get a draw.) Then the boys' money ran out, and the film hints that the brothers' father had embezzled it from their company. Really? When? How? The movie does not elaborate, and as this documentary project is approved by Tas, I sense it has tiptoed around the issue of Pappas Sr. It would also be interesting to hear Hawk's side of the story: he is conspicuous by his absence. A sad, involving story. If it becomes a feature, Andrew Garfield would have to play Tas.
