Harrison Ford has confirmed his return for "Blade Runner 2", sequel to the critically acclaimed 1982 sci-fi movie "Blade Runner".

With Ford--best known for playing the role of Han Solo in Star Wars movies--returning to the sequel, fans are having a hard time to sustain their excitement regarding the mystery behind Ford's character, Rick Deckard, which was left unexplained in the Ridley Scott directed original movie. Denis Villeneuve, director of the upcoming sequel, is planning to resolve this mystery in "Blade Runner 2".

There have been a number of interpretations of the noir sci-fi that had released 33 years ago. One of it is the possibility of Deckard being a "replicant" (artificial humans hiding among the society) whom he hunted.

However, there are a lot of other interpretations and fan theories that have been argued over vociferously by the sci-fi community for decades.

Villeneuve, in an interview with Crave Online at the Toronto International Film Festival, said: "Now that I am on the other side of the fence, I cannot answer. The thing I must say is that I love mystery. I love shadows. I love doubts. I would just want to say to the fans that we will take care of that mystery. I will take care of it."

"Blade Runner 2" is all set to undergo production in summer 2016. Michael Green and Hampton Fancher, who co-wrote the first movie, will be writing the screenplay. The story will be based on an idea by Fancher and Ridley Scott, who is returning as the producer.

Not much of the story is revealed yet other than the fact that it will be set decades after the events of the first movie. Villeneuve's comments hint that it may deal more intimately with human nature.

The first movie was a loose adaptation of Philip K Dick's "Do Androids Dream of Electric Sheep?". However, "Blade Runner 2" will be in continuation with the movie and will shift the universe even further than Dick's novel. A franchise based on the sequel is also under consideration.

Wired UK has reported that apart from Harrison Ford, Ryan Gosling, who acted in "Drive and Only God Forgives" has also joined the cast in an undisclosed role. Rumours indicate that Gosling may be the new lead and Deckard won't make an appearance before the final act of the film.

The release date is not yet finalised. As it will be a mid-2016 shoot, most probably the movie would be out by 2018.
