The original "Blade Runner" movie was released in 1982, but is still largely popular up to now because of the many versions the film has undergone over the years.

"Blade Runner" is a popular science-fiction thriller film about a dystopian earth. The movie was set in murky and miserable Los Angeles. It centered on Rick Deckard, a Blade Runner, who was appointed to haunt and kill "replicants" - robots or androids who look like humans.

Blade Runner's original movie was not intended to have a happy ending but during the final editing of the film in 1982, a more pleasing end was added to the movie.

However, actor Harrison Ford who played the main character, Rick Deckard, seemed not to agree with the last minute changes.

Allegedly, the famous actor did not perform well on the voiceovers for the new ending so that those would no longer be considered.

To satisfy the fans, the original but more troubling ending was incorporated in the 2007 version of Blade Runner, The Final Cut.

Now, Blade Runner is back in production for a sequel that will paint 2047 version of a toxic Earth. The still yet untitled sequel is being referred to as simply, Blade Runner 2.

The movie's director, Denis Villeneuve, said the movie will tackle the effects of the toxic form of the planet on the human race; the ocean, rain, snow and practically everything, already toxic.

The movie already has a stellar cast and crew.

For the cast, it is already confirmed in November 2015 that Ryan Gosling will play the main character in the film. However, the actor of the original movie, Harrison Ford, is also rumored to be included.

Behind the scenes, "Sicario" director, Denis Villeneuve and director of photography, Roger Deakins will be working hand in hand. While, Blade Runner's original director, Ridley Scott, is the story writer.

However, Villeneuve said that he might not have the final cut for the sequel. In this case, will fans see another happy ending and again wait for years for the true ending, just like the case for the original movie?

Blade Runner 2 release date will be on Oct. 5, 2017.
