Who is your favourite director, why, and what do you consider their magnum opus?

[Vavorasag]

I think these are the ones i consider my personal favorites

Francis Ford Coppola - Apocalypse Now
Christopher Nolan - The Dark Knight
Peter Weir - The Truman Show
Milos Forman - One Flew Over the Cuckoo's Nest
Ridley Scott - Gladiator
Frank Darabont - The Shawshank Redemption
David Fincher - Fight Club
Quentin Tarantino - Pulp Fiction
Stanley Kubrick - Dr. Strangelove or: How i Learned to Stop Worrying and Love the Bomb
Steven Spielberg - Saving Private Ryan
Orson Welles - Citizen Kane
Guillermo del Toro - Pan's Labyrinth
Brian de Palma - Scarface
Peter Jackson - LOTR: Return of the King
Danny Boyle - Trainspotting

i'm also really shocked no one has mention David Lynch so far and I think his magnum opus would be a tie between Mulholland Drive and Twin Peaks
