Emily Blunt has opened up about the ‘real issues’ she had with Cillian Murphy while filming blockbuster ‘Oppenheimer’, and it’s not quite what you might think.

The famous actress confided during a recent interview people, revealed that she found the Irish actor’s stunning eyes very distracting for her and difficult to concentrate on her work. His deep blue eyes clearly appealed to Blunt, and co-star Matt Damon agreed there was something powerful about his eyes. “It’s really a problem when you’re working on a scene with Killian,” Damon told People.

Damon also admitted to being attracted to Murphy’s appearance. “Sometimes she finds herself just swimming in his eyes,” Damon said.

Blunt, 40, commented on the situation and made a comparison to explain the powerful nature of Killian’s eyes.

“It’s like ‘Ocean Eyes’ by Billie Eilish. We just hum it all day long,” Blunt said.

Murphy, 47, spoke up with a shy, juvenile demeanor in conversations about his good looks.

“It’s not that blue!” Murphy quipped, according to People.

Murphy is doing the acting of life as Oppenheimer. Brandt plays Oppenheimer’s troubled wife Kitty in the newly released film. (Related: Cillian Murphy reveals the only lead role he secretly wanted to play)
