Found in the the R-rated trailer for "300" is a single frame of test footage of "Rorschach" from Alan Moore's Hugo award winning graphic novel "Watchmen." It looks like Zack Snyder suitably impressed Warner Bros with "300" to let him direct "Watchmen."
I'm excited and apprehensive at the same time. The complex stories of Moore and the level of detail shown by his artists make for the finest graphic novels, with a very cinematic quality. However Moore's work really makes use of the comic medium, and film adaptations of his work can fall short. I would love to see Moore brought on to develop film projects, but he a bit of a recluse, and has washed his hands of the entire film industry, along with much of the comic industry.
