Rumors are flying about the upcoming comic book adaptations of Iron Man, The Watchman (both coming out in 2005), and Black Widow (2006). It's being said the X-Men and X2 screenplay writer David Hayter is writing the scripts for all three films, as well as moving into the directors chair for The Watchmen and Black Widow.
I've heard that too. Be smart to do so, but it all depends on the story they go with. If they go with the Phoenix sage it could be a two parter: with one part being released in the summer in the other in the late fall (like Matrix Reloaded and Revolutions were).
