12 Things That Almost Completely Changed 2016’s Biggest Movies

2. Nick Wilde Was The Original Protagonist - Zootopia

The Original Plan: The original script saw fox con-man Nick Wilde as the movie's protagonist, while bunny cop Judy Hopps was a supporting player.

What Happened?: Test screenings found audiences unable to fully connect with Nick as the main character, considering he's a bit of an a**hole, and when Judy received more positive notices, Disney decided to switch-up the hero-sidekick dynamic.

Did It Work?: Over a billion dollars in box office receipts and some of the year's best reviews say a resounding yes. Watching the final film, it's really difficult to imagine it going any other way, especially in regard to that central dynamic.
