Oh hey, another trailer about a guy wandering around an empty Earth. And like Oblivion this one stars a major Scientologist. Kind of a weird coincidence, huh?
After Earth's trailer actually has more of a Scientology vibe than Oblivion's - the idea of fear being a construct seems to fit perfectly in the scifi religion's thoughts on thetans. So maybe this film is the Scientology propaganda we've been waiting for since Battlefield Earth.
As a movie it looks okay. What's the exact hook here? Is it just Robinson Crusoe On Earth? Is there more to it? This trailer hints at some kind of alien threat (or maybe it's Will Smith's own people trying to kill him for unlocking the secrets of Earth), but all I know for sure is that the film will be chock full of CGI monkeys.
