“We haven’t met Ridley,” Kosove said. “but the thought of re-engaging with his artistic vision is very exciting, and [him directing] is something we think would be wonderful.”
"We never would want to remake it — but they do think there’s a rich vein of material for a prequel or sequel, which they will be entitled to make.”
I wouldn't be shocked to see Ridley actually consider the project as it could end up disastrous to his legacy if someone makes a bad film based on the world he created. Curious enough both Kosove and Johnson produced Christopher Nolan's Insomnia a director who I said before would be capable of expanding Ridley's world.
Previously SlashFilm reported that Travis Wright (Eagle Eye) had been working with producer Bud Yorkin on a Blade Runner sequel. Wright going as far as writing a treatment for it. Yorkin just sold the rights so it's unknown if that script development was involved in the acquisition. So there is a possibility of at least a rough outline for another film currently out there. Yet I would expect Warner Bros. to enlist some heavy weight writers to come up with their own pitches as the script is going to be the biggest asset for this project.
