So I was awake the other morning at a bout 3 and could not get back to sleep. The webbook was laying, blinking, on the flor next to the bed, so inspired I spent a little time fiddling with some data from the Internet Movie Database.
They have a top 250 rating system which requires a large number of people to rate a movie before it makes the list, then they use some Boolian magic to come up with a sound set of answers. Bec ause of the nature of the site it is biased to Holywood films, but plenty of non-english language films make it in there.
If we ignore the 2000 to 2009 data, I am not sure where the cut off is for the rating to be about the last film I watched and when it becames the best film I watched - I remember a few ears back teh BBC held a vote for the best single ever and most of the top 10 were from the previous 5 years with the Spicegirls, or some boy band being No1 single of all time - better even that such things as White Christmas, Bohemian Rhapsody etc. So it is reasonable to exclude the last 10 years from consideration.
We get from the top 250
1920's 7 films 2.8%
1930's 14 films 5.6%
1940's 26 films 10.4%
1950's 36 films 14.4%
1960's 23 films 9.2%
1970's 25 films 10.0%
1980's 26 films 10.4%
1990's 36 films 14.4%
2000's 57 films 22.8%
So It is reasonable to factor down the 2000 films because of their newness but a pretty stable mix from 1940's to date
In the top ten there are
1950's 1
1960's 1
1970's 3
1980's 1
1990's 3
2000's 1
Playing by the (arbitrary) rule of ignoring the 2000's we can add
1940's 1
So out of the 50,000plus films made since the 1920's seems every era produces a similar number of gems.
