Alok started it all (though he took his cue from here. And then Jai went and expanded the list (while cheating dreadfully - including several extras, like a DVD crammed with goodies by calling them "Honourable Mentions'. HMs forsooth. He only wanted to include all directors' oevres.)
But worse than these guys are the people who comment, and lazily use the space to make lists a mile long.
Now here's the challenge I'm setting myself. I'm naming 25 films that these two haven't mentioned (commenters' favourites don't count. They should have done a post on their blogs). I'm excluding Copeland's list because it's a list of nominees and not his personal favourites. It appears to have had a nominating committee and other complex procedures, including votes and things.
So here goes. Excluding only English, Hindi, Tamil and Telugu films, the top 25 in no particular order:
Viridiana - LUis Bunuel
Stalker - Andrei Tarkovsky
Ashik Kerib - Sergei Paradjanov
Night Train - Jerzy Kawalerowicz
Man of Marble - Anrdezej Wajda
Fireman's Ball - Milos Forman
Nine Months - Marta Meszaros
Elektra - Miklos Jansco
Love Film - Istvan Szabo
Dark Habits - Pedro Almodavar
Triumph of the Will - Leni Riefensthal
Fitzcarraldo - Werner Herzog
Alice In The City - Wim Wenders
Winter Light- Ingmar Bergman
Notre Musique- Jean-Luc Godard
Last Year At Marienbad - Alain Resnais
A Man Escaped - Robert Bresson
Lucia - Humberto Solas
Memories of Underdevelopment - Tomas Guttierez Alea
Flowers of Shanghai - Hou Hsiao-Hsien
In The Mood For Love - Wong Kar-Wai
Hana-bi - Takeshi Kitano
Autumn Afternoon - Yasujiro Ozu
Take Care Of Your Scarf Tatyana - Aki Kaurismaki
Red Desert - Michaelangelo Antonioni
Dammit! That's 25 and there's still more to go.
I hadn't even begun India: Subarnarekha, Titash, Goopy Gyne, Tukaram, Amma Ariyan, Firingoti.
Haven't mentioned so many directors, even, so many countries (Iran, and Kiarostami, without whom any list is pretty meaningless.)
I also note how few comtemporary directors' work I've chosen, which either means their worth is not yet certain, or that I'm conditioned by a text book idea of cinema's top films.
The trouble with such exercises is, it always leaves you feeling you've done no one justice.
