What was the last feature film that was created using only analog processes?

by deechin

I'm sure it's relatively easy to find the first films that used digital processes, but I'm curious as to what films were the last to use only analog processes.

To clarify, I am asking what was the last film created entirely using only analog processes? That is to say: without any DIT, non-linear editing, digital sound or VFX, etc.
