For Skulls, I'm still holding out hope the film is not promoted as a Predator film, but rather a mysterious period piece monster film. But alas, if they do wear "Predator" on their promotional sleeve, please don't show us the creature, not even in the trailer(s).
If it is full disclosure that they're indeed going for, I would definitely love something in the vein of this for the teaser, but alas, trailer narration has gone the way of the dinosaurs as of late.
