'Yellowstone' star Kelly Reilly says she doesn't always agree with Taylor Sheridan's vision for Beth: 'There are still things that I read and I didn't expect'

• Kelly Reilly doesn't always agree with "Yellowstone" creator Taylor Sheridan's vision for Beth Dutton.
• The actor discussed Beth's character arc in a season five Blu-ray/DVD featurette.

"Yellowstone" star Kelly Reilly said she doesn't always agree with cocreator and showrunner Taylor Sheridan's vision for her character, Beth Dutton.

In a featurette clip that appears on the Blu-ray and DVD release of "Yellowstone" season five, part one, Reilly spoke about the shocking storylines and unexpected developments her character has experienced since the series began.

The interview was conducted before it was announced that season five would be the show's very last, and before the SAG-AFTRA strike began.

Reilly said that Sheridan — who has written every episode of the show since season two — doesn't share storyline details ahead of time, something she said makes the process of working on the show "fascinating."

Nevertheless, Sheridan's method of working has also resulted in a few surprises for the actor, who has been portraying the only daughter of Montana cattle rancher-turned-governor John Dutton (Kevin Costner) since the Paramount Network drama debuted in 2018.

"I'm coming to it almost the same as the audience," Reilly said. "I mean, I have my hopes and thoughts for the character. Also, as I've played her for over five years now, I feel like I know her so well, but I'm still learning."

"There are still things that I read and I didn't expect, or sometimes I wish for something else for her, but that's the same as the audience," the actor said.

"We're all sort of beholden to the vision of the storyteller and we serve the story," she continued. "Who knows what's going to happen? I find that exciting as an actor."

Beth has had her fair share of jaw-dropping moments in the show since it began.

In season three it was revealed that she couldn't have children because her adopted brother, Jamie (Wes Bentley), had a doctor give her a hysterectomy as a teenager.

Elsewhere, it was revealed that her mother died when she was a child after Beth accidentally spooked her horse while the two were out on a ride together — an incident which led Beth to contemplate suicide years later.

More generally, Beth's capriciousness and underlying insecurity have led to her making questionable decisions in her personal life, causing her to repeatedly sabotage her relationship with Rip Wheeler (Cole Hauser).

In a separate behind-the-scenes clip, Reilly cast doubt on Beth and Rip ending up together, despite the fact the fan-favorite couple tied the knot in the season four finale.

"Beth is haunted by her past," said Reilly. "She has a lot of regrets and she has a lot of secrets that he doesn't know."

"So there is something that is under the surface that will one day, I'm sure, come, and she's probably certain that she will lose him," she added.

"Yellowstone" season five, part one, is available on DVD and Blu-ray now.
