Raking round the internet I stumbled upon this trailer. It spoke to me in a way that trailers don't normally. First, it didn't feel like I had just watched the film, or seen all the best bits and second it built up a real sense of excitement, the same kind of excitement I had for this kind of stuff as a sci-fi loving teenager.
The thing that grabbed me the most was the sense of old-school sci-fi, not Star-trek/Star Wars space opera stuff, more like 2001 or Planet of the Apes. I'm lookin' forward to this one!
