Other than George Lucas and his constant work-in-progress tinkering with the Star Wars films, has there been a movie presented in as many versions than Blade Runner? Wikipedia lists seven, but it seems like there have been hundreds.

Well, guess what? While there isn't a lot of information out there yet, it looks like Scott is revisiting the story again in some fashion:

After revisiting his classic Alien with the upcoming 3D Fox film Prometheus, Ridley Scott is committing to direct and produce a film that advances his other seminal and groundbreaking science fiction film. Scott has signed on to direct and produce a new installment of Blade Runner....

I’m not getting a clear sense at this point whether Scott intends to do a sequel or a prequel to the 1982 film that was loosely based on the Philip K. Dick novel Do Androids Dream of Electric Sheep? Also unclear is whether they start fresh or reach out to Harrison Ford. The original took place in dystopian Los Angeles in 2019, in which organic superhuman robots called replicants escaped and are hiding somewhere on earth. Ford played Richard Deckard, a burnt out blade runner assigned to hunt them down. His tired life gets altered when he himself falls for one of the replicants and struggles to keep her from being destroyed.

The film was not a blockbuster when first released—it grossed $32 million in its original run—but the film has gained esteem over time. From the bleak but breathtaking visuals to the complex storyline and themes of mortality, Blade Runner became a classic. There has periodically been talks of doing a sequel but those never really went anywhere. After injecting state of the art 3D in reviving Alien, imagine what Scott can do with Blade Runner? Now, the filmmaker is ready to engage.

Scott is already working on a new take on the Alien saga, Prometheus, that apparently not part of the direct narrative, but related somehow, and that might be a better way to go with Blade Runner, as well. Maybe someone wants to see a straight remake, jazzed up with 3D, CGI, and all the other new filmmaking tricks, but I certainly don't.
