I found this trailer of the Watchmen movie today. Note how many of the clips mirror frames in the graphic novel. I also found it interesting how some of the costumes are different, like Laurie's, Dan's, and Veidt's. They're much more spandex-y, perhaps to make the movie seem more modern? Laurie's costume in the graphic novel, though probably risque back in the 80s, isn't too unusual now. Perhaps her new costume is meant to reflect the sex appeal her character is supposed to have. I also noticed that Dan seems rather fit in the trailer; in the comic he looked somewhat overweight. Again, this is probably to appeal to society's traditional views of superheroes. Veidt's costume is very different in color...any reason for this?
The old trailer is here, if anyone hasn't seen it. Some of the scenes are the same as in this newer trailer.
