^What would constitute a faithful adaptation of
I, Robot, though? Which stories would it adapt? I suppose maybe you could do an adaptation of "Evidence" and "The Evitable Conflict," focusing on Susan Calvin and Steven Byerly, but then that's just an adaptation of those two stories, not of
I, Robot as a whole. Maybe you could find a way to fold in Powell and Donovan.
Here's what
Wikipedia says about Ellison's script:
Ellison's script builds a framework around Asimov's short stories that involves a reporter named Robert Bratenahl tracking down information about Susan Calvin's alleged former lover Stephen Byerly. Asimov's stories are presented as flashbacks that differ from the originals in their stronger emphasis on Calvin's character. Ellison placed Calvin into stories in which she did not originally appear and fleshed out her character's role in ones where she did.
But to me that seems just as artificial as the interview conceit that unified the stories in
I, Robot to begin with. My problem with the idea of "an adaptation of
I, Robot" is that
I, Robot isn't really a single specific or unique thing. It's just a selection of nine of Asimov's thirty-plus positronic-robot short stories. It contains fewer than half of the stories about Susan Calvin; it's basically the Powell-Donovan stories plus a selection of Susan Calvin stories plus "Robbie," which had nothing to do with either in its original form (though the version in the collection has a scene with the teenage Susan Calvin tacked on). And Asimov didn't even choose or want the title; he objected to it because it was already the title of a story by Ernest and Otto Binder (the basis of the
Outer Limits episode of that name and its later remake). Asimov wanted to call it
Mind and Iron, which frankly is a far more awesome title. So
I, Robot doesn't really constitute a single unified or cohesive thing. It's a semi-arbitrary sampling of a small percentage of Asimov's robot stories.
I think if you're going to do a movie that's a compilation of Susan Calvin's life story, you shouldn't base it on the stories in
I, Robot and rewrite them to include Susan; it would make more sense to base it on the dozen-ish Susan Calvin stories as a whole regardless of what collection they appeared in. But I'm not sure adapting an anthology, trying to craft a single narrative out of a bunch of separate stories, is really a good idea. Richard Matheson made a respectable attempt at it in the 1980 TV miniseries of
The Martian Chronicles, but even that didn't really feel like a cohesive whole.
