Hearing that Zack Snyder (of 300 fame) was tackling the classic work of the Watchmen inspires a closer look long before we get to see it in 2009. The movie adaptation already has its website all fired up and running, it is a blog really with commentary from Dave Gibbons visiting the set and Zack Snyder on his use of stoyboards (several boards included).
The Watchmen Graphic Novel itself is a definitive classic, not just for comic lovers, but for readers of all kinds I think. Following a quick check of where the movie is upto (we are still so far out that there isnt alot of info really) - I dug out my copy and was suitably inspired again by how really awesome the work is. The story by Alan Moore combined with Dave Gibbons' visuals make it perhaps my all-time favourite and one of the key reasons I collected comics for a while back in my uni days. It won a Hugo award if memory serves :-)
There are plenty of images out there on the web to show what Dave created visually, but to get Alan's story you need to read the whole thing - masterful, multilayered, complex and thought-provoking.
Here are 3 of the covers from the initial publication (which form the chapter start pages in the graphic novel I know and love).
