During a candid discussion at Deadline's Contenders TV Panel, Mirren revealed that she embarked on this unprecedented journey with little knowledge of her character or the storyline. She confessed that series creator Taylor Sheridan has a unique approach to character development, often tailoring roles to fit the actors chosen to portray them.
This unconventional method presented an intriguing challenge for Mirren, who admitted, "For the first time in my life, I wasn't given a script. I had no idea what it was going to be, and likewise for Harrison [Ford]." Despite the uncertainty, Mirren and Ford were drawn to the project and agreed to participate, trusting Sheridan's vision. However, the absence of a script left them in a state of both flattery and apprehension, as they awaited the revelation of their characters' identities and narratives.
Mirren, who portrays Cara Dutton in 1923, finally obtained a glimpse into her character's world when she met with Sheridan to delve deeper into the series. Describing the moment she received the script as "amazing," she expressed her delight upon discovering the intricacies of Cara's persona. While Mirren introduced a personal touch by infusing an Irish accent into Cara's portrayal, she commended the exceptional quality of the writing, emphasizing, "Apart from that, honestly, it's amazing writing, and what's on the page, it arrives and it's kind of perfect. It's extraordinary."
