I tried my hardest to limit it to just ten but every time i cut someone off the list i felt as though the list was incomplete. It is impossible to definitively say anyone is the best at anything its comes down to opinion and this is mind feel free to remake the list to your liking.
It is near impossible to say anyone is the best director of all time but i can say that Martin Scorsese is the most Consistently great. If i were to list all the great movies he has made I would have to list almost all of them, and it is defiantly debatable that listing all of them would be justified. From Mean Streets to Hugo, Scorsese has proven to be a master of cinema and the greatest story teller of our time. Anyone who loves film loves Scorsese.

The most successful director of all time not just a incredible director but a outstanding business man. The only bad thing that he ever made was unintentional, that was a Hollywood based around franchises and merchandising. Without him we would not have the Hollywood we know today whether you view that as a good thing or a bad thing you can not blame him for making movies that were successful. see more on Steven Spielberg
There is no doubt James Cameron is a incredible director his ability to innovate and to capture the essence of imagination is unmatched, but personally i feel he is just not a great writer and that's why his movies like avatar are criticized an way he is overlooked as the amazing director he is because the poor writing drags the quality of the movies down, but he truly is one of the top ten directors alive, but just an okay writer. see more on James Cameron
Woody Allen is one of the great intellectual minds of our time. If there was true justice in this world, in the future he will be remembered as we remember Shakespeare today see more on Woody Allen
The Godfather Trilogy. What else is truly needed to be said to justify him being in the top five except maybe Apocalypse Now. see more on Francis Ford Coppola
Quentin Tarantino is a great example of a director who thinks outside the box. In Reservoir Dogs he changed the genre of heist films by leaving out the heist , in Pulp Fiction he shined a new light on crime, and in Inglorious Basterds he rewrote history. see more on Quentin Tarantino
Christopher Nolan is the most promising new director of the 21st century. He personally Turened a dead Franchise into possibly the greatest superhero series of all time. he saw promise in Heath Ledger who's only other major roll was Brokeback Mountain and then he drew out a Oscar winning performance. in memento he blew minds, in dark knight he put them back together,in incepetion he completely destroyed them .only time will tell what will come of this promising director but my guess is in ten years he will be universally considered one of the greatest directors of all time. see more on Christopher Nolan
