Actor Carsten Norgaard who plays an oil driller in the upcoming Aliens vs. Predator says the special effects stunts were quite dangerous. "What was so incredible was that we had four of these huge continental jet engines, like the biggest ones in Europe [blowing on us]," he told Sci Fi Wire. "When you [turn] those on, I'm telling you, you cannot stand. You're virtually flying away. Then you add [artificial] snow. It's like a blizzard. I had to scrape snow out of the eyes [in between takes]. You definitely get the feeling that you're in an incredible, ruthless environment."
Meanwhile, concept artist Patrick Tatopoulos posted some concept art (filled with spoilers) that he prepared for the film. Check it out here.
