Kelly Reilly on the final season of "Yellowstone" and what's next for Beth Dutton

It's Yellowstone week here at CBS Mornings. Boy, we had a good time all week. Actors from the hit #1 TV show. You heard me, the hit #1 TV show in the country. It's joined us first on CBS Mornings to talk about the show's epic return. And everybody keeps using that word. Epic actor Kelly Reilly plays a fierce. That's one way to describe her best Dutton, the only daughter of John Dutton, played of course by Kevin Costner. In the mid season finale of season 5, she confronts her backstabbing brother Jamie. He's treacherous too. And his manipulative lawyer girlfriend after they plotted to remove their governor father from office. Enjoying your Marinette, every inch of him. OK, so it's war. War is over, Beth. No, Jamie. War is just beginning. War is just beginning. And guess what? She ain't lying. First on CBS mornings, Kelly Riley, we're glad to say, is here. Hello, Kelly Riley, hello. Thank you for having me. We, I, I really want to know how you feel about Beth because she is so insane. But she's so fun to watch and we still like her. Why? I want to know what you think about her. Oh, gosh, there's so much to her. I mean, there's just, she's not just one thing. She's like, she's like 10 women in one. There is obviously we know her as, like you said, insane and fierce, but there is such a deep soul and incredible depth of heart and love and devotion for her family, father. I love her. I love, I mean, I can be infuriated with her, but I love her. I remember there was a Alan Rickman, one of my favourite actors. He, he had a, he, there was something he said about you cannot play a character and judge them. You can't, you cannot. It's impossible. If you judge them, you can't become them. And I understood that because I I had to. I just had to understand her. I don't necessarily have to agree with her, but she's a hell. She's a lot of fun and she's a wild ride. She is a wild ride. It was so interesting when we were all watching the clip together. We were all impressed by the intensity and how fierce she is. And you said she's so sad, which I guess is that sympathy you have for her. She breaks my heart. I'm so moved by her and I think over the years, over the seasons, you've you're able to sort of unpeel the the layers and get to see why she does some of the things she does. Well, you say look at her back story told everything you need to know about her. That's right. I mean, this is a woman who she grew up with brothers on this ranch. It's a very harsh, brutal environment. She was afraid of horses as a child, which she's not, you know, great for a daughter of a ranching family. And she there was an accident where she accidentally killed her own mother with, you know, being afraid of horses caused the horse to rear up and land on her mother's chest. And as her mother lay there on the ground dying, she said, this is your fault. I mean, what does that do to a psyche? So there was a lot for me to like. And yet, as you say, she has this incredible depth of love within her heart that you actually see even when she's doing things that you might find reprehensible or terrible. And part of that is manifesting the relationship that you have with RIP, right? And, and, and Cole Hauser was here and I asked him, what's it like to know that people on in Halloween dress up like you? And people have T-shirts that say love me like Beth loves RIP Breakdown. That love and the chemistry that you both have on the show, which is on fire. It's like RIP loves Beth. We gotta get that part. Yeah. Right. Right. I mean, they're both savages, right? I mean, they really are. But they are. So they're so fiercely protective of one another. And I think to have that and also that history, they loved each other from 15 years old. We know the story that she got pregnant and he doesn't know, he doesn't know. And in a way, and I don't want to give too much away to the audience, but is there is there anything that could come between RIP and Beth? I'm sure that question, I mean, maybe I that's to you know, Taylor has has has yet to give that to RIP that information. So whether or not it stays in the vault of Beth's heart forever, she doesn't want to hurt him. Yeah, that would hurt him. You know, the first time I heard you speak #1 She's also in here the movie here. Yeah, which we love. Robin, you're here and you're playing Tom's mother. So that's a whole different layer of, of, of Kelly's work. But I'm so fascinated by your accent. The first time I heard, did you, were you intimidated by going from the British accent to doing the Montana accent? Did you put a lot of work into it because you were so spot on in your delivery? Well, thank you. I worked with a great dialect coach, so she helps me. But it's not the first time I've played American. So I yeah, I was in flight and True Detective, so it's not. And I married to an American. I live in New York, so I'm surrounded, yeah, by a lot of. I hear you all the time. Yeah. And I sometimes think I sound like I'm that person in the Mid-Atlantic has that American twang, which my mum always, and my brother, or they'll call me up and say you sound so American like I don't. And you take that as an insult or a cop. No, I, well, I the Mid-Atlantic thing is horrible. I'd rather just sound fully American or fully British, but sure. Yeah. No, I so I, it. Everything about Beth was intimidating to begin with for me. And that's the least of all her accent. That was that was the least thing I was. I wanted to get it right. But the season's wrapping up in her final seconds here. How do you feel about a Beth RIP spin off possibility? Yes, please. Yeah. Well, I want you all to see these next 6 episodes and see where it lands. Are they satisfying to you? The last sick. It's incredibly satisfying. Everybody has said that. It's very catharsic. Very. Yes, it does go high as if. Yeah, we take the roof off. And then there is something about it that is really beautiful and poetic, which ultimately is. Yeah, I can't wait either. Bravo, Kelly. Bravo cheering you on, always. Yellowstone returns this Sunday. We all get to see it November 10th on Paramount Network at 8:00 Eastern and Pacific.
