Guy who did the screenplay for this has written the screenplays for the following:
Schindler's List
Searching for Bobby Fischer
Clear and Present Danger
Gangs of New York
Money Ball
The Fincher directed Girl with the Dragon Tattoo
American Gangster
If this sucks it wont be because of a bad script, it will be due to the studio fucking with it like Kingdom of Heaven. Anyways you can always tell a Scott movie from looking at it, it sure looks like it has brilliant Cinematography, and I am willing to place the blame of Prometheus on Lindelof, so I am cautiously optimistic for this.
