The promotional campaign for the upcoming Sin City sequel has suffered another setback after U.S. Tv bosses rejected a trailer for the film over actress Eva Green's sexy wardrobe.

The Casino Royale star initially hit headlines in May (14) when officials at the Motion Picture Association of America (Mpaa) banned an advertising poster for Sin City: A Dame to Kill For, because it featured Green brandishing a gun while wearing a sheer white robe over her bare breasts.

Movie bosses had to re-edit the billboard picture to make the outfit appear less raunchy in order to meet the Mpaa's censorship guidelines, but now they are facing the prospect of also having to alter Green's appearance in the trailer for the upcoming film amid concerns from ABC network executives, who have refused to air the preview footage due to Green's attire.

Marketing chiefs at the movie's distributor Dimension Films are appealing the decision.

A source tells the New York Daily News, "Abc rejected a trailer, saying Green appears to be naked in the same sheer, white nightgown. Dimension was told to remove the offending footage if they want the trailer to air."

Green previously admitted she was baffled by the furore caused by the sexy film poster, telling Vanity Fair magazine, "I find it a bit odd. It seems like it's all just publicity - a lot of noise for nothing. You have so many more violent things in the movie business and this is kind of soft. I'm not naked. It's suggested. I find it really sexy, actually. It's kind of beautiful. But if it shocks people, I don't know what to do about it. I don't want to upset anybody."

Sin City: A Dame to Kill For, which co-stars Jessica Alba, Mickey Rourke and Bruce Willis, is due to open in cinemas in late August (14).
