I have not. Though I consider myself a comic book nerd, the better description would probably be super hero geek and Marvel fanboy. Most of my knowledge of comics comes from secondary sources like compendiums or wikipedia and I rarely read the source material.

Vince and I both liked 300, by the way, and he is a big Snyder fan based on it and the zombie flick he directed. This, to him, would be like Joss adapting "The Sandman" into a major motion picture and having Nat play Death.
