That was just the movie. In the book he killed a hill-troll chieftain by stabbing it when it tried to kill his Gondorian friend who's name escapes me. He did not climb on it's back. Trolls are only weak (logically) in the head. Eyes and open mouth make tempting targets to a skilled marksman. Maybe a massive resistance to arrows in general and a weakness "critical hit" to arrows to the head.
