Speaking with the British newspaper i in 2023, Lowden described Ronan as "one of the best actors in the world" and said having her at home makes it "a lot easier" for him to prepare for auditions.

"Sometimes she gives a better performance than me off camera and you're a bit like, 'Can you, erm, not?'" he joked.

Lowden also compared Ronan to the acting version of a Ferrari. "My first love is actors," he told the outlet. "And when you're given a Ferrari like her, it's all about how you make everything good for the Ferrari to show off. Don't make a Ferrari do what a Renault Clio does. It's a dreadful analogy but they're like gold dust, good actors. When there's someone like that, you just have to facilitate them and you will get gold. And my God, did we."

Speaking to Harper's Bazaar, Ronan said in reaction to these comments, "When a person you respect as much as I do him says that, it means more than anyone else's opinion."
