Really good news consider at this point in Prometheus's development the R rating was still up for debate, with a PG13 cut made along side it, and the decision to release the R rated version not made until after filming. Not sure what Gaf's stance is on Prometheus, but I thought it was the third best in the series and personally can't wait for some more big budget R rated sci-fi.
When a reporter commented on fans being interested in the horror aspect of the Alien series, Ridley Scott responded “that’s why I’m doing it. I’m going to do pretty Hard R.” He further elaborates that he wants to do a scene with the same sort of impact that Alien’s original chestburst scene had but something “much worse.”
