Chinatown or Harry Potter and the Half-Blood Prince?

Are you a fan of Chinatown? Of Harry Potter and the Half-Blood Prince as well? Prove it! Select which quote belongs to which movie and see how good you are:

- Why is it, when something happens, it is always you three?

- Believe me, Professor. I've been asking myself the same question for six years.

- Has it ever crossed your brilliant mind that I don't want to do this anymore?

- Whether it has or it hasn't is irrelevant; you gave me your word.

Isn't that something? Middle of a drought and the water commissioner drowns. Only in L.A.

- Hey! She's only interested in you because she thinks you're the Chosen One.

- But I am the Chosen One... Sorry... kidding!

I goddamn near lost my nose. And I like it. I like breathing through it. And I still think you're hiding something.

You're a very nosy fellow, kitty cat. Huh? You know what happens to nosy fellows? Huh? No? Wanna guess? Huh? No? Okay. They lose their noses.

What can I tell you, kid? You're right. When you're right, you're right, and you're right.
