Replacers of the Lost Screenwriter

I haven't heard a lot about the "live-action Robotech movie." However, today I did manage to run across a new tidbit, that the writers Alfred Gough and Miles Millar have become attached to the project... somehow, it's not quite the same as hearing Lawrence Kasdan was involved. I suppose, of course, that he just may not have worked out, and yet, I did notice the article mentioning how "Gough and Millar bring action and geek cred to the table," and asking myself how The Mummy: Tomb of the Dragon Emperor, Spider-Man 2, and even producing seven seasons of "Smallville" is much more "credible" than The Empire Strikes Back, Raiders of the Lost Ark, and Return of the Jedi... (Of course, as I've told myself before, those projects of Kasdan's were a quarter of a century in the past.)
