Why do people want to connect Blade Runner and Alien?

[Kradan]

Alien featured an android and AI. It was not about androids and AI.

But now IT IS. How you gonna to live with it?

Alien is about a monster killing people on a spaceship.

References, nothing more. Scott is stealing from himself which is kinda sad.

Alien is about a monster killing people on a spaceship.

First movie? Yes, no denies.

But now it's 40-year running franchise and there should be room for story evolution, shouldn't it?

[Ingwar]

Chappie and Terminator are part of the same universe. Both are about robots

Or y'know, he's an artist that's interested in exploring the same themes throughout his work.

Agreed

Of course - but that doesn't mean Alien is now about AI.  Covenant is about people encountering an robot who made some monsters, and a third film may complete David's arc.  But it still doesn't make the whole saga about AI.

[Ingwar]

I don't mind if he wants to explore the same themes. Fair enough. But using exactly the same references is odd or just lazy. Not mentioning David saying Roy Batty's line that's the spirit. It's just too obvious and simple. No need for that.

Well, he loves self-references for sure 

Below, David (Covenant) & Sibylla (Kingdom of Heaven)

I actually like that shoot with David . I thought about Sibylla straight away while watching Covenant at the cinema.

[The Old One]

I think it's possible for two correlating series to be about different things whilst existing in the same universe, without characters  directly crossing over or effecting each other in fact- I think that's an interesting idea. I'm not saying that Alien and Blade Runner do but they easily could, as much as Prometheus with memory viewing technology and Aliens can co-exist, where they doubt Ripley's story.

Unless that technology was lost with the Prometheus and it was also a scientific research platform as well as Peter Weyland's luxury yacht, the same could be done to work around any potential inconsistencies between Alien and Blade Runner.

[Ingwar]

They could but they don't. It is what it is. Two different universes. Nothing can change that. Interesting? Maybe. Possible? No.

[The Old One]

Nothing can change that, except the same could've been said of Predator at one stage.

It's not like Blade Runner's a hot property, but it is a well-respected one, I could easily see Disney buying it on the cheap.

[Ingwar]

We cannot forget that Blade Runner is based upon Dick's novel. It's not original story. It comes from the book. You cannot merge book adaptation (with its copy rights and so on) with original and nothing-to-do-with-that-universe movie (Alien). Unless you want to have another Dracula vs. Frankenstein ...
