So Zootopia opens here tomorrow...
10 years ago
A few weeks ahead of the US and a month ahead of the UK. Chances are I will see something slightly different than you will see, as was the case with Prometheus and a few others. But anyhow, I'll be sure to spoil it completely for you tomorrow :) The Chilean market is of interest to movie publishers because they can drop an early release there, sniff around for commentary, and then do some last-minute edits to prep it for the main release.
FA+

We in Canada don't have it until the 4th of March.
And why would it be altered for?
Stuff the production crew doesn't see because their eyes have been burned out on it for the years they took to make the edit. Continuity, flow, etc. Stuff they needed the audience to notice but they failed, etc.
Anyway you enjoy the film.
