A new film on B.C.’s old growth forests, with a focus on the Fairy Creek blockades, is making its debut at the Whistler Film Festival this month.   Before They Fall, directed by Cam MacArthur, is produced by Whistler-based Ecologyst Films.  MacArthur said he wasn’t actually setting out to make a film about the protests around the Fairy Creek watershed, which has become one of the largest acts of civil disobedience in Canadian history.  “It was supposed to be an eight-minute-long short film,” MacArthur said. “A month into production, [the Fairy Creek blockade] just blew up and we knew there was no telling this story without making Fairy Creek a huge part of it. So now it’s half the film.”   …Protesters arrived to the site, a two-hour drive from Victoria, over a year ago to prevent Surrey-based logging company Teal-Jones Group from working.
