Welcome to Ice Planet.
To answer a question I had about lighting, I often use a backdrop image on a computer screen or a television screen (both flat), with whatever light I have in the room. Sometimes it’s from above; sometimes it’s from the sides, depending on what’s available. It’s not exactly a well-thought-out process, but I’m glad it’s effective.
The visual where Galanos is being chased by the Ice Planet team is loosely based on the opening scene of The Thing (1982), in which a dog is being hunted across the Antarctic ice by a helicopter.
