The soldier whose parachute didn't open, and who fell to his death, was Dutch from the first film!Poor guy survived the events of the first movie with sheer badassery only to splat onto the ground due to faulty equipment.
This is the Yautja's home planet!just cause it'd be too badass not to see!
The idea of 'Seasons' isn't quite accurate.They don't drop in one batch at a time, they continually drop in batches of animals to hunt. This is partially confirmed by Noland having been there for nearly forty years, describes ten seasons, yet the dead soldier at the beginning is only 'two weeks' dead (roughly) and they drop in a new batch right at the end. Perhaps they hunt for all of what amounts to a 'summer', then take the rest of the year off. So assuming a much bigger planet than ours, Noland's 'ten seasons' equating to about one every four Earth years instead becomes one a year accounting for an extra long year.
Those picked from Earth are replaced with biological duplicates.Most of the cast could go missing without causing a stir, but the authorities would definitely notice an inmate vanishing from death row. The humans picked to be hunted would be lifted out and replaced with dead duplicates. Their autopsies would conclude death from bullet wounds, embolisms, or some other cause that would not be mysterious under the circumstances.
The dead guy, whose trap the group sprang, was killed by Nolan.He probably pretended to be the guys friend before killing him for his stuff when the trap was complete.
The hunting-ground seen here is just one of many that the Predators have seeded with other worlds' native life.The plant life shown was introduced from Earth, explaining how Edwin could identify the toxic flower. The weird gray-skinned creature that Isabelle missed shooting was intended to be released into a different hunting-ground zone — one with vegetation native to its home planet — but was dropped in the wrong area due to some technical glitch, possibly the same one that'd prevented one of the humans' chutes from opening. If there's a sequel, it may feature Royce and Isabelle making their way cross-country to other artificially-cultivated hunting grounds, each filled with a different world's selection of alien vegetation and animals.
The characters were held in stasis for a loooooong time before being released into the hunting preserve.It's implausible to think that Noland could have survived in an environment that harsh since the Vietnam War, and he doesn't look old enough to have been the type of elite, seasoned Special Forces soldier that the Predators would have been interested in abducting at the time. Moreover, it'd be pretty strange for the Predators to change their previous habit of hunting humans on Earth for no good reason. Rather, they may have been collecting potential human prey for centuries and putting them into stasis, in preparation for when humans' technology and population-growth inevitably left it unsuitable as a hunting ground. Assuming Royce and Isabelle ever do get back to Earth, they'll find that it's been centuries since they were abducted, there's no more wilderness to speak of, and humans can now shoot down the Predators' ships.
It was overcast when they crossed the first clearing.When they finally see the Alien Sky they've already been in clearings. It was ovvercast then, so they didn't notice until the plot required it.
