More than half a century into his career, Harrison Ford has no plans of slowing down.

The Academy Award nominee opened up about his love for "the challenge" of making film and TV at age 80 as he stars in Yellowstone's prequel spin-off 1923, premiering Sunday on Paramount Network, while speaking to The New York Times.

"I'm 80, and I'm playing 77," Ford joked. "It's a bit of a stretch."

In 1923, Ford and Helen Mirren lead a new generation of the Dutton family as they navigate the hardships of the era, including Western Expansion, Prohibition and the Great Depression.

Ford has also been busy with his upcoming performances in Indiana Jones and the Dial of Destiny, MCU's Captain America: New World Order and Thunderbolts, as well as the Apple TV+ series Shrinking. 1923 marks Ford's first starring television role.

"I've been working pretty much back-to-back, which is not what I normally do," he said. "I don't know how it happened. But it happened."

And the Star Wars icon has no intention of retiring any time soon. "I love it. I love the challenge and the process of making a movie. I feel at home. It's what I've spent my life doing," he said.

"I'm here to sell a movie," Ford added. "I don't want to reinvent myself. I just want to work."

"I admire her work and her person [now], and I have all the same degree of admiration for her as I did then," Ford said at the Los Angeles premiere of 1923 earlier this month. "She's wonderful, she's just a lovely person, and so it's been both a professional pleasure and a personal pleasure working with her again."

1923 premieres Sunday on Paramount+ and Paramount Network, following the latest episode of Yellowstone at 8 p.m. ET.
