LMAO!!!
Not so much from them because they are the soup of the day....but imagine a Hulk script written by Peter David and Greg Pak; an Iron Man Script by Bob Layton and David Michelinie; Captain America by Ed Brubaker; Daredevil by Frank Miller; X-Men by Chris Claremont; etc....
Imagine them being involved in the casting...
Actually, I would love to see one (or more) of the iconic writers being heavily involved in writing a film adaptation of one of their iconic stories.
While the Avengers movie and the Iron Man movies were really good, I would still like to see a great adaptation of an iconic story because, I was disappointed with X2 and X3.
Chris Claremont actually studied acting in college. According to old interviews he wanted to be an actor and originally just intended on writing Uncanny X-Men temporarily. So, he might be able to write a movie script. Though, he might need a co-writer to tweak it. But, imagine a much more faithful adaption of the Dark Phoenix Saga, or, an adaption of the Mutant Massacre storyline.
I would also love to see a Giffen and DeMatteis style Justice League America/International movie. Their Despero storyline from JLA #38-#42 could work for a movie. It shows them (Giffen and DeMatteis) at their most serious, but, at the same time has some of the funniest moments from their run. Also, the news story intro from issue #38 could be used to create an abbreviated (and very funny) intro to the characters.
J. M. DeMatteis has actual television script writing experience. He wrote for The Real Ghostbusters and other shows.
