If you were asked to come up with the most prominent film director of the 21st century and the name was not Christopher Nolan, you would be climbing a rather slippery slope.
After his breakout second feature Memento, Nolan began a steady rise as the most revered of directors of the last century. When coming up with this list, I knew sticking to the “one film per director” rule would prove most difficult with him, because even his lesser movies are still worth watching. That said, when you make a film that is possibly the most popular of all films this century, one of the best sequels ever made, the best of its genre (superhero/comic books), and, after not getting a Best Picture nomination, even (allegedly) made the Academy start having more than five Best Picture nominees,…yeah, I had to go with The Dark Knight.
Nothing else to say
