In case you’ve ever wondered what it was like to film a snow storm scene in the middle of sunny Los Angeles, this is what it’s like. As you, the actor, staggers down the fake street façade emoting the heck out of the scene, a crew is rolling beside you, with a machine that funnels into a wind machine tons of gypsum or shredded paper or bleached corn flakes or mica or asbestos or whatever looks good on camera. I’d imagine that stuff gets into every nook and cranny, so you wouldn’t want to mess your lines too much and have to do it over, would you?
