Yes, well -- it certainly wasn't originally. One of the most revelatory segments in the movie shows us a scene from Bruce Brown's famous ode to surfing The Endless Summer that takes place in African and would seem to indicate that the natives there had never before seen surfers until the white boys showed up to amaze them. According to this film, that scene was simply not true.
We also learn about The Inkwell (above, and not the one on Martha's Vineyard, but a section of Southern California beach near Santa Monica that was frequented by Blacks back in the 1950s and 60s -- until it was suddenly off limits to them -- and one of the early Black American surfers Nick Gabaldon. Among the several Black surfers the moviemaker highlights (in truth, there just aren't that many of them) is Sal Masekela, who tells us a lot of interesting stuff, most piquantly in his statement that he has never understood the phrase about how you "catch a wave," On the contrary, he explains, it is always "the wave that catches you."
Trespass Productions, opens today, Friday, September 23, in New York City at the Quad Cinema. And elsewhere, I would hope. This movie has far too much to say to both blacks and whites (all of us in between) for it not to be distributed more widely.
