Cat Taylor talked to the effects guys on the show and compiled a list of practical effects and the technology that brings them about. Here is a favourite of mine, click thru to the entire piece to read the rest of the paragraphs.
Snow Business provides all the snow candles for the show. What is a snow candle? A certain type of paper is soaked in a chemical that makes it burn slowly, and as it does, the candle creates a very fine ash that the SFX team spins in galvanized buckets. If they find the right wind, it drifts nicely through shot; if the wind is not moving in their favor, you get crew members’ faces full of fake snow and a lot of complaints. According to Barras, snow is one of his favourite things to do, but also one of the hardest natural phenomena to recreate. “I took fake snow to Iceland,” he told me, “but we never had to use it.”
The post comes with a bonus shot (by HBO’s Helen Sloan) from the explosion stunt shot used in the Blackwater episode.
Hear Me Roar: Thanks Cat, practical effects and other such tricks of the trade are some of my most favourite nuggets from behind the scenes.
