A wildfire breaks out on the season two debut of Arctic Air tonight at 9 p.m. on CBC, with “real-life fire, smoke and trees falling down in front of us” say leads Adam Beach and Pascale Hutton about a 10-day shoot up north last August, supplemented by elements in the Vancouver area and computer-generated effects. This classic adventure series tries to film as many exteriors as it can in Yellowknife, block shooting two episodes at a time which overlap into four episodes, making the season seem like one long movie, according to Beach and Hutton. But the bulk of filming is done in Vancouver on permanent sets like the DC-3 fuselage (used for green-screen flying) in Aldergrove and at small airports around the Fraser Valley. Last season our downtown memorably played itself for one episode, the wonderfully-titled “Vancouver is Such a Screwed-up City”, but not this time. When our northern pilots do go south in the second season, it will be to Burnaby pretending to be Calgary for the penultimate episode guest-starring Dragons’ Den Dragon and best-selling personal finance author David Chilton as himself.  I had the chance to interview all three CBC stars at CBC Vancouver’s Open House and Food Bank Day late last year.
