'Blade Runner 2049': Harrison Ford and Ryan Gosling promise 'emotionally deep' sequel

Blade Runner 2049 stars Harrison Ford and Ryan Gosling discussed their trip to the future Monday — and they topped it all off with a new trailer for the anticipated sci-fi sequel.

This latest installment is directed by Denis Villeneuve, who was also a part of the Monday panel broadcast on Facebook. (Check out the panel, and the new trailer below.)

For Ford, his first complex scene with Gosling was a surprisingly powerful moment on set.

"It was a scene about history that transpired between the last time you saw the character and how you see him now, and they reference between the two characters, and it was unexpectedly deep, emotionally deep, and really rich," said Ford.

Ford said the film "acknowledges and deals with some of the ethical considerations that technology presents us with," adding, "there's no such thing as a free lunch and we're really talking about both the benefit of technology and the social consequences of it."

After revisiting Indiana Jones and Han Solo, Ford touched on what in particular was different about revisiting the world of Ridley Scott's 1982 original.

"The character is woven into the story in a way that intrigued me. There's a very strong emotional context and the relationship between the character Deckard that I play and other characters, I found fascinating," said Ford. "It's interesting to develop a character after a period of time ...; it was a very gratifying experience."

Gosling said the practical effects, real sets, and limited use of green screen made it a particularly impressive experience.

"You were completely immersed in this universe you had grown up imagining and watching," said Gosling. "The trick for me was to not be impressed by it on camera, because it was supposed to be my everyday reality as though I'd known nothing else. But of course I'd never worked in this way or on that scale, so it was pretty overwhelming."

Villeneuve addressed what the film still has to say about humanity, decades after the original.

"We are still exploring the themes of memories and empathy. That's the deeper tissues of where the movie evolves. What the movie's about in relationship of what it means to be human," said Villeneuve.

Blade Runner 2049 is set for release on Oct. 6.
