I’ve made no bones about it; Alex Proyas is a personal favorite of mine. How can you not appreciate the guy who did “The Crow” (still one of the best comic book movies of all time) and the glorious and criminally underappreciated “Dark City”? Proyas’ latest is the Nicolas Cage sci-fi thriller “Knowing”, and during press junkets for the movie he talked about “The Tripods”, a movie based on a series of young adult books that Proyas hopes to turn into a trilogy.
