Robert Downey Jr. highlights unique qualities of 'Oppenheimer' costar Emily Blunt

Robert Downey Jr. has showered Emily Blunt with praise for her remarkable talent and humor.

On Thursday, April 30, Downey Jr. attended the Hollywood Walk of Fame ceremony for Blunt and Stanley Tucci, where he expressed his love for her.

The 61-year-old American actor began his speech by saying, "Tucci, by the way, congrats to you. Now, let me lay into your girl.” It was a reference to their relationship, as Tucci is not only her longtime friend; he is also married to Felicity Blunt, Emily’s older sister.

Articulating his thoughts for his Oppenheimer co-star, he said, "Emily is an outright blunt object. She is the girlfriend you never had in high school. She's the scene partner you will never forget, and she's the wife you can't resent [John] Krasinski for landing because he's equally dynamic and this guy's impossible not to love.”

"And I honestly think that this self-protective feature of their matrimony couldn't have been planned, but it just works a treat and preserves itself,” Downey Jr. noted.

The Avengers: Doomsday actor went on to add, "She's a blunt instrument of calm, professional hilarity. We survived [Christopher] Nolan together. Sophisticated empathy, deep understanding, essentially, she's a blunt force."

It is pertinent to mention that Blunt and Krasinski, who have been married since 2010, welcomed two daughters together, 12-year-old Hazel and 9-year-old Violet.
