Ryan, who is also a producer on the film, said, "I remember breaking the scene after Jodie's first three lines and looking over at Shawn to make sure that he was watching because I couldn't believe what I was seeing."
"She took it to a whole new level. Jodie is one of those one-in-a-billion actors. She can do anything and be anything. Her on her worst day is like me at (my peak)."
"I hate to use this term but she has the X factor," he added. "Working with her felt like working with Meryl Streep at the beginning of her career."
Agreeing with the comparison to the "Devil Wears Prada" star, Shawn shared, "She's a special talent and quite limitless in what she can do. Watching her audition was a revelation."
The glowing remarks have left Jodie stunned.
"What?! They did not (say that). That's very kind," she said. "I mean - a young Meryl Streep, uh, no. That's very sweet of them though."
"Working with Shawn and Ryan was just so much fun," she continued. "They created an atmosphere where I could be fearless, silly, and playful."
The "Killing Eve" actress recalled feeling like a "zombie" when she auditioned for the movie.
She told Australia's Marie Claire magazine, "I remember (the audition) so distinctly. I'd just finished a six-month shoot on Killing Eve and flew to New York like a bit of a zombie."
"I spent the flight thinking about what I could do wrong and if I should call Ryan 'Mr. Reynolds'. I hadn't done a film before; it felt so much bigger than myself."
