Last films of great directors

[UltraMario9]

Its always pleasant to see a great filmmaker end on a high note, it's also equally disappointing when the last effort could be considered their worst.

Which do you consider the best and worst final efforts?


For me...

Best:
Once Upon A Time In America
Eyes Wide Shut

Worst:
A Countess From Hong Kong



Here's an article with a lot of suggestions.
