Under 17 and thinking that "Prometheus" looks like the must-see movie of the summer? Some potentially bad news: director Ridley Scott says that the future blockbuster could get slapped with an audience-restricting R-rating.

In an interview with Empire, which has "Prometheus" on its May cover, Scott revealed that the film's rating is still up for debate.

"Right now I don't know where we are," Scott said. "The question is, do you go for the PG-13, or do you go for what it should be, which is R? Financially it makes quite a difference, or the risk makes quite a difference, and yet you also have to apply the question -- if you soften it, will you financially suffer? As opposed to just going for the throat and gambling. Essentially, it's kinda R."

Scott allowed that it's not just blood and guts that would force an R-rating, but "stressful" ideas. Considering the trailer for "Prometheus" featured the tag line "They went looking for our beginning, what they found could be our end," he ain't kidding!

Of course, even if "Prometheus" does wind up with an R-rating, that doesn't necessarily mean its hopes for box-office supremacy will die like John Hurt in "Alien." Sci-fi films like "The Matrix" and "The Matrix Reloaded" were able to overcome R-ratings to earn major grosses, while comedies like "The Hangover" and "The Hangover Part II" didn't fare too badly either.

"Prometheus" -- rated either R or PG-13 -- will hit theaters on June 8.
