During the battle between Arnie and the Predator at the end of the movie, the Predator starts to figure out Arnie's mud trick. Arnie tracks some green blood into a cave where the Predator sneaks up behind him. Arnie throws a flash grenade and makes his way out of the cave where he begins to leap, dramatically, to a very CROOKED tree branch high above some water. The scene cuts to the Predator firing at Arnie and then back to Arnie in mid flight towards the branch, a now very STRAIGHT and horizontally erect tree branch!
