Talking on his official site, “I Robot” Director Alex Proyas revealed that he envisions the Will Smith starrer as the first in a series of movies.

"Many years ago a chap named Peter Rice and I where sitting in a cafe somewhere in LA discussing all our favorite science fiction stories and novels and the ones that would be cool to make into movies. Peter is a good friend and at the time was an exec at 20th Century Fox (these days he runs Searchlight) - I think this roughly coincided with when I was developing DARK CITY at Fox, before we took it to New Line. I, ROBOT was the one we kept coming back to, and though Peter tried to secure the rights they were unavailable at the time. A few years passed and Peter came to me with a really cool script called HARDWIRED, a spec written by Jeff Vintar, that read kind of like the Asimov story he never wrote.

Coincidentally the rights to I, ROBOT became available and it was decided to merge the basic plot of HARDWIRED with the ideas, concepts and some of the characters of the Asimov stories - as a literal translation or combination of the 9 stories into a single movie proved unfeasible. With HARDWIRED we had the specific movie narrative the project needed. However HARDWIRED was really just a spine for our story, countless drafts were done to bring the story in line with the I, ROBOT universe and it was re-conceived as a prequel or an "early days at USR" take on Asimov.

That's the overly simplistic version. One day I'll write the book and go into more detail. By the way, I, ROBOT was created with the intention of it being the first in a series of films - early on I decided there was no way a single 2 hour movie could do justice to all the ideas Asimov explored in his collection of stories. Will there be more films? - we'll have to wait and see"

Thanks to Dark Horizons for the heads up.
