Have you seen the movie Zootopia? I heard it's great!
疯狂动物城是一座独一无二的现代动物都市。每种动物在这里都有自己的居所，比如富丽堂皇的撒哈拉广场，或者常年严寒的冰川镇。它就像一座大熔炉，动物们在这里和平共处——无论是大象还是小老鼠，只要你努力，都能在此闯出一番名堂。不过乐观的警官兔朱迪（金妮弗•古德温 Ginnifer Goodwin 配音）却发现，作为史上第一任兔子警官，要和一群强硬的大块头动物警察合作可不是件容易事。为了证明自己，她决心侦破一桩神秘案件；追寻真相的路上她被迫与口若悬河、谎技高超的狐尼克（杰森•贝特曼 Jason Bateman 配音）联手，却发现这桩案件背后隐藏着一个意欲颠覆动物城的巨大阴谋……
In a city of anthropomorphic animals, a rookie bunny cop and a cynical con artist fox must work together to uncover a conspiracy. From the largest elephant to the smallest shrew, the city of Zootopia is a mammal metropolis where various animals live and thrive. When Judy Hopps becomes the first rabbit to join the police force, she quickly learns how tough it is to enforce the law. Determined to prove herself, Judy jumps at the opportunity to solve a mysterious case. Unfortunately, that means working with Nick Wilde, a wily fox who makes her job even harder.
Judy Hopps: I thought this city would be a perfect place where everyone got along and anyone could be anything. Turns out, life's a little bit more complicated than a slogan on a bumper sticker. Real life is messy. We all have limitations. We all make mistakes. Which means, hey, glass half full, we all have a lot in common. And the more we try to understand one another, the more exceptional each of us will be. But we have to try. So no matter what kind of person you are, I implore you: Try. Try to make the world a better place. Look inside yourself and recognize that change starts with you.
