KGNB News has just recently posted up an article saying that Predators has done some filming at Lake Gorge:
“A little bit of Hollywood came to Comal County last week when a film crew from Austin used a portion of the Canyon Lake Gorge to film scenes for a new sci-fi thriller move coming to theatres next summer. Troublemaker Studios, a film company run by director and producer Robert Rodriguez, is currently in production of the next chapter of the Predator films, and after a month of filming in Hawaii, their next stop was Canyon Lake.”
So it isn’t going to be entirely green screen minus the Hawaii scenes as previously thought. Thanks to Pinkman for the news.
