With fame on the backburner, the 45-year-old has spent his time relishing in fatherhood. Since trading in the bright lights of Los Angeles for the serenity of the English countryside, the 40 Days and 40 Nights star and his wife Tamsin Egerton—who tied the knot in 2021—raise their four daughters in a suburban town outside of London.

“The thing I am most proud of is that I’m a father of three and I have a good relationship with my partner and a great family life,” he told Mr. Porter in a 2021 interview, three years before announcing the arrival of their fourth child. “And I’m still able to do good work and, as I’ve got older, the characters have become more interesting.”

And although he’s recently been thrust back into the spotlight with buzzworthy roles in Black Mirror and Oppenheimer, he’s found a balance with his personal and professional life.

After all, when Hartnett returned to the red carpet in February for the 2024 SAG Awards, he immediately turned the attention to his Oppenheimer castmates, including Cillian Murphy, Emily Blunt, Florence Pugh and director Christopher Nolan.

“Being in the film with these other actors and just Chris deciding to choose me to play this role was the winning goal,” he exclusively told Live From E!: SAG Awards host Laverne Cox. “We had a fun time making the film and then for it to be so phenomenally received and to have it be nominated by our peers for acting categories, across the board, is great.”
