Can your friends or family tell when you’re being genuine with them? Sometimes. I think it’s just the tone of my voice that throws people off. Zooey Deschanel recently told me, “Everything that you say to someone sounds like you’re mocking them.” I was like, “But I’m not.” And she was like, “Even when you just said that, it sounded like you were mocking me.”

You have another movie coming out this month, “Life After Beth,” in which you play a zombie. Did you watch a lot of classic zombie movies to prepare for that? I decided to purposely not watch anything and just kind of wing it. Because I have this brewing demonic monstrous energy inside of me, and I’ve never really had a way to express it. So I didn’t prepare at all. I just went with my instincts. I was like, I’m just going to see what happens when I tap into my monster self.

I doubt many people think, Aubrey Plaza, yeah, she’s got a real rage inside her. That’s a bit surprising. I’m holding a lot of things in. Let’s just leave it at that. Every movie that I do is cathartic, because in my real life I do have a problem with, you know, emoting and letting my feelings out.

The movie also stars your B.F.F., Anna Kendrick. Is it fair to describe her as your B.F.F.? For your purposes, yes. Why not?

You’ve gone on a trip to Mexico with her. You were her Oscars date. You tweet to each other adorably. It seems only a matter of time before you get matching tattoos. It’s true. We have a very deep connection, and it’s hard to have friendships in this town. We have a mutual respect for each other, professionally and personally. And we’re also sexually attracted to each other. That’s another kind of layer of our relationship. We always talk about how we were born in the wrong era of Hollywood. I feel like we could have really ruled the 1930s MGM studio system. If we’d been signed with MGM, we would have owned that [expletive]. But it’s not really like that anymore.
