Over at prometheusforum they have screen captures of a conversation via twitter with someone who has seen an advance screening of the movie.
I will not post any spoilers but I will provide a link for anyone interested. Proceed at your own risk!
Don`t say i didn`t warn you, but I have to admit I read them and it takes nothing away from the movie. I`ll still see it on opening night.
UPDATE: Confirmed as pure bullshit, seen the movie this person`s account is wrong.
