We went into the studio and we had igloos made of fibreglass, obviously they couldn't be made of snow. We had fibreglass igloos and it's an extraordinary feeling being in an igloo because you have no sense of distance because every... everything is round and white and in one side as you come in the igloo, always on the left, is a small fire burning in a piece of soapstone... soapstone and... and they use whale oil or seal oil and they burn a... a wick of moss, and this provides light at night and they also cook by it, there's a little cooking stove hanging just above this flame. And of course, just above the fire you get a certain amount of melting from the snow but otherwise the temp... temperature inside the igloo is below freezing and that's the way they live. And it, you know, it was wonderful, sort of studying how... how the igloo [sic] lived years ago because this hardly exists now, living in igloos except occasionally when they go on hunting expeditions. So we were recreating the way they lived... the picture was set in the 1930s.
