Kevin Peter Hall could make a creature threatening or gentle through the way he moved inside a cumbersome suit. We value the menace he brings to Predator, even when the human characters are thin.
Fi1m perspective
In Predator (1987), Kevin Peter Hall has to give an alien personality while his own face is largely concealed. His movement does much of the acting, and the cumbersome suit gives him plenty to work against. We rate the performance highly: the creature has enough character to sustain our interest as well as threaten the humans. At 7 ft 2 in, Hall had an obvious advantage in suggesting danger, but height alone cannot make a character.
The early parts were already pointing him towards this sort of work: a mutant bear in Prophecy (1979), then the alien in Without Warning (1980). Harry and the Hendersons (1987) gave him a gentler creature to play. As Harry, the sasquatch, he brought expression to another cumbersome costume. That contrast with Predator, released the same year, matters: it gives us a reason to value his choices beyond the practical business of being tall enough for the part.
John McTiernan gives him a useful setting in Predator: a jungle commando film that becomes an alien hunt. We were frightened because Hall's physical menace makes the danger to Schwarzenegger's convincingly vulnerable soldier feel real. The director builds the suspense, but a creature performer still has to justify the waiting when the creature is there to be seen. Hall does, and that is a substantial part of why we recommend the film despite its crude dialogue and thin characterisation.
He returned as the alien in Predator 2 (1990). Prominent unmasked parts were scarce, which limits what we can judge of him outside creature work. That is no reason to treat these performances as interchangeable: Harry and the Predator have different temperaments, despite the disguises. Start with Predator, then try Harry and the Hendersons for the gentler performance.
