It is possible but why would she die? Maybe in a JL Kingdom Come movie but that will make Superman more Emotional and Sad or JL Injustice movie that will turn Superman in a dictator, both version will be criticize to death.
But I doubt they will kill Lois in the DCEU they will probably make a Father & Son Superman movie just like the Rebirth Superman comics. And that will be a family oriented action movie including Lois.

I don't believe she will die at all. And what does Amy's age have to do with anything? She doesn't even look her age.

Possible? Yeah sure.
But what would that serve?
=w=

Hmm. Gotta say I didn't see it quite that way - but if they were thinking of going down an Injustice route and then changed their minds they could certainly use that as a device to get around having to follow-up on Flash's time-travel visit, I guess.
I originally thought the Extended Cut would include an entire subplot set in the future.
Maybe they were hinting at future story lines, but if Lois' eventual death wasn't the drowning, then the scene feels completely random to this movie.

Because I was under the assumption that had she drowned in BVS, Superman would have gone nuts. But he saved her, so shouldn't that dark "INJUSTICE" inspired future no longer exist?

If you're talking about the Flash's time travel scene, I don't think that will come into play. Or is it supposed to? Because I was under the assumption that had she drowned in BVS, Superman would have gone nuts. But he saved her, so shouldn't that dark "INJUSTICE" inspired future no longer exist? It should have been Batman who saved Lois, but I figured it was just sloppy writing. Are they planning to adapt Injustice story lines in the future? I'd rather the two heroes just unite and fight evil. We don't need another movie where Batman has to battle Superman.

She was killed by the Joker in Kingdom Come (seen in flashback); she died in Injustice: Gods Among Us (Superman was tricked into killing her by the Joker - which kicked off the whole Superman-tyrant thing) - both of which are alternate futures. Golden age Lois died in Infinite Crisis.

She never died in the comics, did she? Like Gwen Stacy?

I'm only expecting a death because Amy is older than 40.
It's cynical of me, but I'm not expecting the best out of the boardroom that chose Gal Gadot.

Probably too early. Leave it for the Superman movie or JL2.

She shouldn't
fcking die at all
. That'd be depressing even by the DCEU's standards.
The villainy you teach me I will execute-and it shall go hard but I will better the instruction.

The Constantine and the greek gods parts should be almost completly excluded from a cinematic version of Injustice. They felt too much like fillers. But they should include a scene where we would see Superman persecute and kill magic users, since they can bring him down. With the exception of Constantine. They could show Batman trying to recruit him and being told to beep off by Constantine, that "to the hell with the world, I only care for my daughter" would make an amazing scene.

I really think that it will look great on the big screen, at least vol 1-3 didn't really like the constantine part.

Not at all

It would be a loss for DC if they didn't go trough with the injustice story.

I think the Cyborg movie's been dropped, hasn't it? But yes, I don't think we'll get a second Superman solo before 2019.

Hopefully that Injustice tease is actually Final Crisis and Darkseid has the Anti-Life Equation.

Agree with every word. I'm pretty sure Darkseid will play a big role in this Injustice based story. I kind of don't want to see any other member turning evil, only Superman

I don't think it's possible to have 'Man of Steel 2' before 2019. Their schedule is full and, from what we know, they don't have a script or a director for that movie. Amy Adams' age doesn't help either. We also know that there won't be Clark Kent in that sequel, cause he's officialy dead in this universe.
I don't think delving into "Injustice" would be a good decision here, there's no room for that. What're they going to do in the 'Cyborg' movie (2020) or 'Green Lantern Corps'? Showing another prequel, origin story, while there's this apocalyptic scenario playing out on Earth in the present time?
Have no idea how they're going to develop this universe, but surely it'll be interesting to watch.
I should add that the 'extended nightmare sequence' from 'BvS' clearly shows that the 'Injustice' storyline in some form is a part of the history of the DC cinematic universe, however how they're going to execute it? Again, no idea.

Exactly. If MoS 2 is before JL 2, they need to explore Clark and Lois relationship some more to give more of a reason to why he would turn evil after Lois dies at some point. If it's after JL 2, then I don't mind her dying in that film. Joker definitely should play a role in that

Agree, my main argument is that, at this point, it would look repetitive, cause Superman has just "died" in the previous movie.
But if that is ever going to happen is this DCEU, I'd like to see the Joker playing a key role in killing Lois.

Too early. I'd say after JL 2

Yeah well beep them! Do evil superman, that would be amazing onscreen

There's also a question of the alternate universe(s), and how that issue is going to play out in the future movies
Yes, I think it's possible we'll see a bit more detail of a
possible
Injustice-like timeline, but I'm sure the 'real' heroes will - as you say - be more upbeat.
