The animated family film Zootopia already dealt with some dark themes—racism, drugs, government conspiracies*—but this clip of an old animation storyboard (with voice acting) shows that it was originally heart-wrenching. In the version that made it to theaters, old suspicions still exist between species that were once predators and those that were once prey, but they live in legal equality. In the old version...well, let's just say this is one of the most depressing kids' birthday parties ever put in a cartoon:
That's right, the original version of Zootopia made the title even more of a flat-out lie. In this draft version, predators lived their lives from the time of puberty onwards with a collar that shocked them if they got excited—even if it was from happiness. No wonder sly fox Nick Wilde is always so cool and collected: if he wasn't, he would be physically punished by an all-seeing state.
*A lot of people think the version of Zootopia that reached theaters is an allegory for the old conspiracy theory about the CIA creating crack cocaine to destroy inner cities and justify harsher crime laws. Hooray, Disney!
