He would straighten his posture, the eyebrow would go up, and I would say, “Patricia.” Instantly. He demands excellence, and it’s a privilege to work with someone who pushes you in that way. We’re similar but we’re also very different beings. Because most of her stuff in the script is stage direction, it’s not dialogue.How much did Night let you know about the character?When I met Night to do the audition I got nothing. The scenes with him in his room were just so intense. As Casey, she brings a quiet strength and wily intelligence to the role. It just happens that those characters and those stories exist in darkness. One of these girls, Casey (Anya Taylor-Joy), is a bit of a black sheep and her own mysterious past is teased throughout the movie.If you don’t know Taylor-Joy yet, you will. I’d have to say it’s a combination of Patricia and Hedwig. But they’re rarely commended as acting showcases, even though a handful of performances in his films serve as near-career highlights for the actors performing them (Bruce Willis in “The Sixth Sense” and “Unbreakable,” Mel Gibson in “Signs,” Bryce Dallas Howard in “The Village”).Shyamalan’s latest mind-bender is “Split,” and features a handful of peerless performances. With Casey, I just heard her voice. She’s so quiet and so observant and has such a strong core strength. Then the reaction that we got at Sundance was so unprecedented. And the reason they can’t figure out my accent is because I don’t have one. She’s so desperate to be a part of the girls that she fetishizes them in a way. And so when I speak English I just mimic whoever I am around. I always knew I loved acting, but now I’m in love with what I do. We did it twice. And I was like, “OK. I never thought, “Now I’m a serious actor and I’m only going to do genre movies.” I just follow my characters. He’s a friend and a mentor but working with him is different. Was it hard for you to learn that dialect?Not at all. Posted January 18, 2017 by Drew TaylorM. One was with a Kanye West song and one was with the song that’s in the movie. So, after I read the script, I knew I was in.Of all of James McAvoy’s personalities, which were the most fun to play against?Ooh … I go mama bear protective over it. It was just one of the girls. He’s changed the way I act, forever. I have to really commend his ability to move his face. Her inner world that she’s built to protect herself is so rich and deep and I really wanted to see if I could challenge myself to communicate with the audience without speaking. Absolutely nothing. It’s the kind of star-making performance that feels like it only comes around every so often. And he just knocked it out of the park. If you had to say, “Which relationship did I enjoy the most?” It would be Hedwig. Nigh Shyamalan next week, including a discussion of the movie’s seriously insane twist. I could tell which character I was talking to just with the flicker of an eyebrow.Really?Oh, yeah. I guess we hit the zeitgeist at the right time.It’s so weird seeing you in modern clothes.And talking with a normal accent.Yes! Night Shyamalan is a director whose films are widely praised for their high concept ingeniousness, beautiful camerawork, and soul recalibrating twists. Anytime she would brush my hair, it would make me extremely uncomfortable. I spoke Spanish until I was 8. And then, when I read the script …Something that is very common for me in all of the characters that I do play is that I love them. But I was also seeing it through Casey’s point-of-view. one last question: Would thou like to live deliciously?I am! It wasn’t even specified who I was reading for. So my scene was the window scene. But I remember seeing Robert, in my puritan gear, covered in blood, and I said, “You know, we made a really cool movie but it’s a shame nobody will ever see it.” And he said, “I know, I know.” We were completely calm about it. That was this morning, right?Yeah!When you were making “The Witch,” did you have any idea it was going to have this impact?Oh, hell no! Instantly, Casey’s voice came so strongly for me I never even considered Marcia or Claire. Bye!”We were told not to explicitly discuss the ending. But that said, it’s been really good fun.What about this character made you think, I have to do this?It’s either an instinctual thing, or my heart goes like this [makes a motion of her heart beating fast]. I loved Casey so much. So I met James, we shook hands, and he proceeded to spoon me on Night’s couch. And I just heard her voice. So, at the end, when he’s flickering through all of the personalities, Casey is done. [Laughs]”Split” is out this Friday. I really did. I grew up my whole life having a thick English accent and I’m here for two minutes and I’m already using the accent. I would just talk to him for two minutes before going up and I’d be fine.OK … So not only was the language super poetic but we had a little boy, Lucas, who was from Yorkshire. “Split” is the story of a man (played by James McAvoy) who suffers from dissociative identity disorder, meaning that he has 23 personalities living in the same body. I feel like a lot of actors couldn’t have done it, because there’s a big possibility for failure. But I can’t remember which Kanye West song it was.Did McAvoy talk you through what he was going to do, or was it a complete surprise?We were lucky enough to have a week of rehearsals prior to filming. And I was done, too. After the take was over I’d say, “It’s James, it’s fine.” But him with the brushing was like, Ahhh, this isn’t fun …Was he actually dancing to a Kanye West song?Yes, he was. I have a real instinct for This is my character and if I don’t do this I am going to die. The first thing I read of anything was sides [specific scenes that are taken from the script], because it’s Night and he’s secret. He’s given me such a love for the craft. I was like, “I don’t understand anything. I have a very strong feeling with directors, too, and I love directors. I will remember this moment for the rest of my life. He wouldn’t have to say anything. And what makes it even more incredible is that it’s following Taylor-Joy’s breakout role in Robert Eggers’s “The Witch” from last year.I got to sit down with Taylor-Joy in New York City to talk about “Split,” what it was like working for Shyamalan, whether or not she knew that “The Witch” would be such a sensation, and, given the movie’s unexpected ending, if she’d be back for further adventures.Moviefone: Most of the movies you’ve made so far have been genre-based. She’s so quiet and, as you can tell, I never shut up. Cool!” But he’s so fearless in this film. I would love to!So you’d do another movie with Night?Oh, absolutely. We’ll have more from writer/director M. With James dancing at you and you have to tell yourself, “You’re scared, you’re scared, this isn’t funny.” But with Patricia, I had such a visceral reaction to her as a person. It’s an intense love and it’s kind of scary sometimes because I’m not very good at sticking up for myself but if you mess with my character, you’re going down. And I would like to preface this by saying everyone that made that movie is my legitimate family. It’s an aspect of my job that I absolutely love — getting to work with these incredible people and create something bigger than yourself. It was the first time I ever felt like I fit in. So he offered me the role, and I said, “Well I have to read the script.” And he said, “But I’ve offered you the role.” I had to tell him that it doesn’t work like that. After Robert, he’s the director who has had the biggest influence on me. His shrink (Betty Buckley) tries to get through to him and, all the while, he has three teenage girls locked up in a subterranean lair. I’ve been so proud of my work thus far, even if other people didn’t like it, but it was my choice and I’m very proud of that. But from the second I met him I thought, I have to work with you. But is there a possibility for you to be a part of future adventures?I would love to. And this is just my life now. It’s super annoying for me and people get irritated with me because they can’t figure out my accent. When you have someone you vibe with like that, it elevates working to a whole other level.Congratulations on your BAFTA nomination. What’s the appeal of these movies for you?I don’t think about it that way.
