Our long national nightmare is over: "Prometheus" has been rated-R by the Motion Picture Association of America for “sci-fi violence including some intense images, and brief language.”

Collider confirmed the news with Twentieth Century Fox after posting a photo of an advance ticket for "Prometheus," which noted the restrictive rating.

This ends weeks of public teeth-gnashing from director Ridley Scott, who took the MPAA to task over some of the films that received PG-13 ratings this year.

"[F]ilms this year that have got PG-13 ratings -- it’s absolutely f--king ludicrous," Scott was quoted as saying by Indiewire's blog Thompson on Hollywood back in April, before adding that the MPAA should get its "house in order.”

Scott had previously said "Prometheus" was "kinda R" -- no kidding, judging by that face-collapsing international trailer -- but worried about how that would affect the financial returns.

"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?" he told Empire in March. "As opposed to just going for the throat and gambling."

Fortunately, Scott is used to gambling with ratings -- and succeeding. His four biggest box office hits -- "Gladiator," "Hannibal," "American Gangster" and "Black Hawk Down" -- were all rated R; meanwhile, Scott's R-rated "Alien" -- the forefather of "Prometheus" -- earned just under $80 million upon its release in 1979. Adjusted for inflation, "Alien" would have made over $235 million at the U.S. box office if were it released in 2012.

"Prometheus" is out in theaters on June 8. For a complete look at HuffPost Entertainment's expansive "Prometheus" coverage, click here.
