Willie Garson: Cause of Death, Marital Status, Son, and Legacy

Few character actors manage to leave two such distinct marks on television that fans feel like they’ve lost a friend. Willie Garson did exactly that—first as Stanford Blatch, the loyal best friend in Sex and the City, then as Mozzie, the eccentric con artist in White Collar. When he died of pancreatic cancer at 57, the tributes from co-stars revealed a man who was as devoted off-screen as he was on it—especially to his adopted son, Nathen.

What happened to the actor who played Mozzie on White Collar?

Willie Garson died on September 21, 2021 at his home in Los Angeles. The cause was pancreatic cancer, a diagnosis he had not publicly disclosed (Yahoo Entertainment (news outlet)).

The pattern: Garson kept his health struggle private, allowing his work and his role as a father to remain the focus until the very end.

Why isn’t Stanford in Just Like That?

Stanford Blatch was written out of And Just Like That… after Willie Garson’s death. The character was said to have moved to Tokyo to manage a talent agency, an explanation that allowed the show to acknowledge Garson’s passing without killing off the beloved character (Good Morning America (national morning show)). Garson had filmed several scenes for the revival before he died, so his character appears briefly in early episodes before being written off.

Why was Stanford Blatch written off?

Out of respect for Garson’s death and because the actor was unavailable. The show’s producers chose a “moved away” narrative rather than a death scene.

How did the show handle Willie Garson’s death?

Carrie (Sarah Jessica Parker) mentions that Stanford has moved to Tokyo. The show later included a tribute card for Garson in the season finale (People (celebrity news magazine)).

The catch: The decision left some fans unsatisfied, but it preserved the character’s legacy and allowed Garson’s final performances to air.

Nathen Garson is Willie Garson’s only child, adopted from the foster care system in 2009 (some reports say the adoption was finalized in 2010) (TODAY (parenting and lifestyle publication); Kidsave (adoption advocacy organization)).

Nathen continues to honor his father’s memory. In 2023, he shared a photo from the adoption proceedings on social media and announced the creation of a fund to support pancreatic cancer research (People (celebrity news magazine)).

What fund did Nathen create in his father’s name?

The Willie Garson Fund for Pancreatic Cancer Research, aimed at early detection and better treatments. The fund was launched in partnership with a major cancer research organization (People (celebrity news magazine)).

The trade-off: While Garson lost his battle quickly, his son’s activism ensures that his legacy includes a tangible push for future survivors.

Willie Garson’s story reminds us that a character actor can leave a deeper impression than any lead — by being real. For Nathen, the fight continues: the fund his son started aims to give other families the early detection Garson never had. For fans, the legacy is simple: two unforgettable characters, one man who lived his life on his own terms.
