Warner released their first movie poster for Watchmen. Drawn by Dave Gibbons, the artist of the Watchmen comic, specifically for Comic-Con 07, it's got the release date in the bottom right and depicts the catalyst for what happens in the comic. Firstshowing.net had an excellent piece on the all things Watchmen at Comic-Con, but I found that Stephen McHattie was added to the cast, presumably as the original Night Owl, from IGN.com. CHUD had the best Snyder interview I've seen yet.
I also checked out the official website of the movie, which points out that Watchmen is the only comic to win the Hugo Award (given to best sci-fi or fantasy work) or to be named Time magazine's "100 Best English Language Novels from 1923 to the Present." (they are sorted alphabetically, but the readers ranked Watchmen 5th; they also made a list of best graphic novels)
