This is a big week for documentaries on Seattle Screens. The big name, of course is the new Frederick Wiseman film, In Jackson Heights which plays Friday through Thursday at the Northwest Film Forum. We’ll have a review of that sometime soon, once we’ve managed to see it. But two other non-fiction films of interest open this week as well. The Grand Illusion is presenting a 2014 restoration of a 1980 updating of a classic 1926 documentary, Moana, the second feature from Robert Flaherty, the man who more or less legitimated documentary filmmaking as an art form with his first feature, Nanook of the North in 1924, while at the same time muddying for all time the distinction between fiction and non-fiction film. A few blocks south on the Ave, the Varsity is playing director Nelson George’s glowing tribute to Misty Copeland, who just this summer became the first African-American principal dancer at the prestigious American Ballet Theatre.
