Aside from the fact that the action in King Arthur: Legend of the Sword looks phenomenal, it also has the telltale appearance of a Guy Ritchie action movie.
It is an effect that the director has become well known for over the course of his career, and he used it to great effect during previous movies like RocknRolla, and Sherlock Holmes: A Game of Shadows.
One thing is very clear: Guy Ritchie is nothing if not distinctive in the filmmaking community, and he likes to set himself apart.
In particular, there is one moment in the trailer in which we see Arthur (Charlie Hunnam) running for his life from an unseen threat in a medieval town.
