Creating all-TIME lists is the pasTIME for TIME.
Ok, that was a futile attempt at being funny, but the list is worth a quick scan. In any case, I haven't seen most of the movies on the list: maybe because many of them seem to be strictly arthouse cinema, or because most of them were made a zillion years before I was born.
Predictably Present: Godfather, The Good the Bad and the Ugly, Casablanca, ET, Pulp Fiction, Star Wars, Schindler's list and Psycho.
Pleasant to Find: Drunken Master, Lord of the Rings.
Plain unpleasant to find: Nemo. ('Tis gud alrite, but all-time greatest? I beg to differ!)
Surprisingly Missing for me: Life is Beautiful, Braveheart, [few others...]
Surprisingly Missing for critics of the critics writing the list: Gone with the Wind ( Reuters )
Our Pride: Apu Triology, Nayakan and Pyaasa.
Update: While looking for the country of Origin of Kandahar (also in the 100), I found another list of Best and Worst movies. This is a list of more recent releases, and ratings are supposedly based on critic's scores. Quite predictably, Godfather tops this one.
