The Motion Picture Association of America (MPAA) has issues a ban on the new "Sin City 2" poster, calling it "too sexy" for the audience the game caters too.

The poster features actress Eva Green and is part of the promotional campaign for her upcoming flick "Sin City: A Dame to Kill For." The poster has been slammed for its nearly-nude content, which shows a sexy Green dressed in a sheer white robe that barely covers her breasts, leaving little to imagination. The sultry poster has been captioned, "I've been especially bad."

According to a Mirror report, the MPAA said the ban was put due to "nudity - curve of under breast and dark nipple/areola circle visible through sheer gown."

It's a fittingly controversial image for a film whose first installment became notorious for its ultra- violence. That film starred Bruce Willis, Jessica Alba and Clive Owen in an ensemble cast shot in eerie monochrome to mimic the style of the comic book by Frank Miller that it was adapted from. Miller also co-directed it, and his gloomy "Dark Knight" comic inspired the current generation of Batman movies.

The upcoming film will be co-directed by Robert Rodriquez and will also star Joseph Gordon-Levitt and Ray Liotta.

A source told E! News that top bosses of the production house are currently negotiating the matter with MPAA executives, though no official press statement has been released yet.

"The movie will submit ads and the MPAA will ask for tweaks to be made," the source revealed. "There's a compromise and that's it."

The movie is slated for an Aug. 22, 2014 release in the United States and Aug. 29, 2014 release in the U.K.

It seems like U.S governing bodies are being more vigilant about the promotional and advertising campaigns that are being presented to audiences. Nudity and sexuality are two factors that are just not acceptable, according to them. Very recently, a new breastfeeding promotional campaign in Mexico faced a lot of criticism for sexualizing celebrities rather than encouraging mothers to nurse their children. Though no ban has been issued in this regard, advertisers and campaigners need to be extra careful about the stuff they put out to their audiences.

Instagram and its celebrity users have also been having quite a lot of feuds over nudity and overexposure issues. Click here to read more about these incidents.
