Ha, tons of people are asking about the fly! First, NOT CG, those are real flies. Here's the lowdown: in several takes over a couple episodes, flies would buzz into the shots, because it's summer in Toronto. Whenever I saw it, I wanted to use it in dailies, because that's something that happens ALL THE FUCKING TIME in reality, but you never see it in TV or movies. Just felt a little messy and real to me. The more I thought about it, the more it also came to represent the corruption of the world all these characters are struggling through. But was just a happy accident. I've read some theories that it's a hero -- ha ha, maybe one day!
