Jeffrey Dean Morgan cast in the film version of Watchmen

My brother just emailed me to let me know that JDM was cast as the Comedian in the film version of the graphic novel Watchmen.  He thought I'd read it.  He was confusing the fact that I'm reading The Sandman series right now.  But you bet I did go right out to Amazon and ordered Watchmen!

Casting News for Watchmen

And from Variety the news that the cast will be unveiled at ComicCon

I wonder if that means JDM will be at ComicCon?
