Pierce Brosnan brought a little piece of his marriage into the DC Extended Universe.

The Golden Globe nominee, 69, revealed that he wore his actual wedding ring while filming the upcoming Black Adam as a tribute to his wife of 21 years, Keely Shaye Brosnan, in a recent interview with Entertainment Tonight.

"This is our wedding ring and this is a watch that Keely bought me many years ago with an inscription that [reads], 'Time flies on love's wings,'" he said. "I decided to wear it for this character. It seemed appropriate."

"The man [has] traversed the ages of time. He's one of the most powerful sorcerers in the DC comic book world. He did have a wife called Enza, and she was even more powerful than him I hear," Pierce then explained, noting that he has "no idea" who might potentially play Enza.

Keely, 59, was touched by her husband's subtle onscreen tribute. "I love those emblems, that he took those with him into the superpower, superhero realm," she gushed.

In Black Adam, Pierce plays Doctor Fate (a.k.a. Kent Nelson), a superhero and Justice Society of America member who wears the Helmet of Fate, wields magic and sets out to confront Dwayne "The Rock" Johnson's titular character, per a description on DC's website.

The actor previously honored his wife on their 21st anniversary in August, sharing a throwback photo from their wedding day. "Happy Anniversary my love @keelyshayebrosnan. We danced that night and still dance the dance today. I could do it all again," he wrote.

Keely previously spoke to PEOPLE about her husband at the New York City premiere of Black Adam on Wednesday, raving that "he's a superhero at home, so why not on the big screen too?"

When asked what makes her husband so super, Keely said: "His heart. He has a big heart, generous, warm, kind heart."

Pierce and Keely tied the knot in 2001 after meeting in 1994, and they share sons Dylan, 25, and Paris, 21.
