A couple of ideas they could use (just theories, nothing more
)
1).
Predator in a different time period --- This has endless possibilities. WW1, WW2, Vietnam War, etc. But not sure how this would fit into it being a sequel unless they do it in the present. Iraq War, perhaps? Maybe too risky.
2).
Predator hunting/chasing Dutch? --- This would be more in line with the film being a direct sequel. A few of these types of ideas where created back when Predator 2 was being made, of course. If I remember correctly, one of the more popular choices was the idea that a Predator would arrive to track down Dutch during a blizzard in NY.
3).
Predator being experimented on, things go wrong. --- These types of stories have worked recently. Example: Ex Machina, Godzilla & Jurassic World. Could be a dumb idea, yes, but if done right it could be an interesting take on the Predator. Would be a flipped scenario, if you think about it. Instead of humans not knowing what they are dealing with, they now know exactly what they are dealing with and despite that, they suffer the consequences.
Anyone have any other ideas? Thoughts?
