Here's an interesting bit of an interview with snyder, looks like his favorite is rorschach. He seems very excited with the project and the character:
Rorschach is awesome, said Snyder. He's the man. He's too violent and so therefore people will see him and be like, 'Gosh, that's not the answer. That way is wrong.' But he's so cool that it's like Apocalypse Now. You look at that movie now and you think, Wow, this is a poem about anti-war and all of that. But then you watch the movie and you're like, Wow, that's awesome. It's that fine line.
I'm just saying, 'What does that mean? What's the implication of that? How is that different from the way the other filmmakers were approaching "Watchmen?"' Snyder asked rhetorically as he showed off the image of his assistant dressed as Rorschach, which he shot as an early test for the flick. I can tell you right now, and I don't know [what other directors planned to do with Watchmen], but I don't think his intentions were to take the frames from the book and kind of try and figure out the cinematic version of them. I find that kind of interesting and exciting.
Snyder reportedly wants to begin filming this spring on the highly anticipated comic project, and rumors persist that hell once again team with his 300 star Gerard Butler, possibly in the role of the doomed Comedian.
