Matt Damon calls wife Luciana 'the greatest thing' in his life after 20 years together

Matt Damon is reflecting on the enduring bond he shares with his wife, Luciana Damon, calling their two-decade marriage "the greatest thing" in his life.

In a recent interview with People, The Odyssey star spoke about the foundation that has kept their relationship strong since the couple first met in 2003.

While avoiding offering relationship advice, Damon acknowledged that every couple's journey is different.

"Boy, I've always loathed to give any advice because I feel everybody's different and everybody's relationship is different," he said.

The Oscar-winning actor credited their lasting marriage to mutual love, trust and respect.

"There's a lot of love and respect underneath the relationship, and a lot of trust. It's built on a very sturdy foundation. We continue to grow and evolve as people, and so that foundation's really everything," Damon shared, before adding, "It's the greatest thing in my life."

Matt and Luciana married in 2005 and are parents to four daughters: Alexia, Isabella, Gia and Stella.

Beyond family life, the couple also work closely together professionally.

Luciana is a partner at Artists' Equity, the production company founded by Damon and longtime friend Ben Affleck.

The actor revealed that his wife has played a key role in his creative process throughout their relationship.

"She's been a part of that for me since I've known her. She reads everything I'm doing. She looks at cuts of movies. I've really relied on her notes for 23 years," Damon said.

He also explained that while he was filming The Odyssey, Luciana was producing Animals, the film directed by Ben Affleck.

"She and Ben have their own work life and creative, professional relationship. We have one all together at the company, but they went off and did this movie while I was away and that's great to see," he added.
