afternoon america," you're going to know our guest from her oscar nominated turn in up in the air. Also as bella swan's bff in the "twilight" series, now she's take on a new role in the animated movie, "paranorman." Please welcome anna kendrick. I'm hearing a siren song in the audience. Keeping it creative. We'll check the boxes. Vampire, check, werewolves, check, now zombies and goefs in paranorman. Tell bus it. This is a film by the people who made coraline. And it's about an 11-year-old boy who can see and speak to the dead, and bullied at school over it. But he has to save his town from a zombie apocalypse. Normal stuff. Yeah your character is the boyfriend of casey affleck's character. The girlfriend -- that will be next -- actually, I did have a crush on him. We meet, and I spend the entire movie kind of like throwing myself at him, and it's quite funny, because he just couldn't be less aware. When you have to do that, we hear the stories that you guys are never actually in the same room. When you have to throw yourself, do they put you in a room so you have that interaction? It's very rare. I got to see my first session with casey. We went that it not knowing what is going on. We've never done an animated film before. By the end of the day, we were kind of competitive over who can do the most humiliating focalization, because you have to do these kind of -- ahh -- all these things at the end of the sentence. Do you have to change your voice making it cartoonny. I wasn't doing it intentionally but when i listened to the movie I was doing a bratty, younger sister kind of voice. Let's listen. Let's take a look. I can't believe this is your plan. I'm supposed to be vegan. There's something moving out there. It's zombies. Oh, no it's not. It's just grown ups. Hide! I know, I had never bee -- and I feel I've missed something in life. Comic con. You're promoting the film -- it's sort of wonderfully crazy? Yes, yes. It's -- you know, it's just absolutely -- the streets are packed. It's like escape from new york. It's -- it's absolutely packed with sand I woulds. I got to go, I loved going. And this year, I was in -- it's like people are walking around in costume like it's really normal. Hi, darse darth vader. And there was a girl in the bathroom having a zombie makeup emergency, she had done some prosthetics stuff over here and it was falling and peel, she had the glue out in the ladies room. I was helping her. She had no idea who I was. It's just like two girls in the bathroom helping each other. That's what goes on in women's rooms. You know what goes on here. We like to make you play games
