Info. regarding the "Space Jockey"

I promised not to say where this info comes from, and I'm sure there will be those who doubt it, but just to clear up a few things: The pale guy we see walking towards the "cannon" as it comes up from the floor and standing over Shaw at the end of the most recent trailer IS the space jockey. It's not a mutated crewmember or something. Also, they got a guy who's about 7'6" to play the jockey. That's still too small IMO compared to the thing we see in the derelict in Alien. Maybe his size is increased digitally in the movie, but it's very possible that it will just be a "tall guy in suit" as they did in Alien. The look of the SJ has really already been revealed in the trailers. I will say that apart from the smooth human head, the body really does look a mix of skeletal and insect- like and very reminiscent of the xenomorph.
