Poverty-stricken Papua New Guinea still largely lacks electricity and running water, but it is extraordinarily rich in gorgeous coastline. When an Australian pilot left a surfboard there in 1980, residents picked it up and ran with it. Before long, surfing was one of the country’s most beloved sports. This deeply entertaining documentary tracks a number of PNG surfers—some of them women—as they train for and participate in a surfing competition that could change their lives. It’s packed with attractive athletes, artsy action, and serious struggle. You’ll love it. (Northwest Film Forum, 1515 12th Ave, www.nwfilmforum.org, 7 and 9 pm, $10)
