It's a shot of Barnabas, seen from Angelique's point of view, framed by her legs. (I guess it was probably considered too racy for a green band trailer.)
It may be too racy for US green band trailer sensibilities - but it's certainly not too racy for here on the forum.
And thanks so much for the link, KMR.
And that article about the trailer vs. the score makes an interesting point because it's certainly true that trailers are often farmed out to companies that have no connection to the studio or to the creators of a film. Who knows - perhaps that really is what happened with DS. Though one would think that if the Warner Brothers' marketing department didn't like what they got from such a company, they would have asked their hire to do it over or perhaps even gone elsewhere. But then, again, who knows? Though so far as the general reaction to the trailer goes, at worst we can say it's been mixed because there are people who hate it, there are people who love it, there are Web sites that question what in the world Warner Brothers was thinking when they put it out, and there are Web sites that endorse it and think it's great.
