If you’ve been rewatching NCIS: Los Angeles and noticed the name “Charlie O’Donnell” in the credits for a young G. Callen, you’re not imagining a connection. That credit leads directly to Charles McHugh O’Donnell — the real-life son of Chris O’Donnell, the actor who plays Callen as an adult. It’s a small but memorable detail that fans often find surprising when they look it up.
This article covers who Charles McHugh O’Donnell is, what we know about his family, his brief appearance on the show, and why there’s so little additional information about him publicly available.
Who Is Charles McHugh O’Donnell?
Charles McHugh O’Donnell is the third of five children born to actor Chris O’Donnell and his wife Caroline Fentress. He is sometimes credited simply as Charlie O’Donnell. He was born on July 11, 2003, in Los Angeles, California.
Beyond his family connection and one confirmed acting credit, Charles is not a public figure in his own right. He doesn’t have a widely known social media presence, and there is no substantial media coverage focused on him individually. Most of what is confirmed about him comes through his father’s public profile and his brief on-screen appearance as a child.
That’s not unusual. Many children of celebrities are known by name and occasionally appear in public alongside their parents, but they don’t seek out — or receive — ongoing media attention. Charles fits that description well.
His Parents and the O’Donnell Family
Charles’s father, Chris O’Donnell, is an American actor with a career spanning more than three decades. He is probably best known for his role as Robin in Batman Forever and Batman & Robin, his acclaimed early performance in Scent of a Woman, and his long-running role as G. Callen in NCIS: Los Angeles.
His mother, Caroline Fentress, married Chris O’Donnell in 1997. The couple has remained together and has built a notably stable family life by Hollywood standards. Together, they have five children:
- Lily Anne O’Donnell — the oldest
- Christopher Eugene O’Donnell Jr. — the second child
- Charles McHugh O’Donnell — the third child
- Finley O’Donnell — the fourth child
- Maeve Frances O’Donnell — the youngest
All five children were present at Chris O’Donnell’s Hollywood Walk of Fame star ceremony, where UPI photo coverage publicly identified each of them by name. It was one of the clearest public confirmations of the full family’s composition. Charles also has a grandmother on his father’s side, Julia O’Donnell, noted in IMDb biography records.
Chris O’Donnell’s Background and What It Means for the Family
To understand the environment Charles grew up in, it helps to know a bit about his father’s own upbringing. Chris O’Donnell was born on June 26, 1970, in Winnetka, Illinois. He was the youngest of seven children in an Irish-American Catholic family.
He attended Loyola Academy in the Chicago area and later studied marketing at Boston College. His roots in a large, faith-oriented, Midwestern household are frequently cited as a major influence on how he has approached his own family life.
Coverage of Chris O’Donnell consistently describes him as someone who prioritizes family stability over Hollywood celebrity culture. The values he grew up with — close family ties, privacy, and a grounded home life — appear to be the same ones he and Caroline have applied while raising their five children.
This context is worth noting because it helps explain why Charles and his siblings are not actively in the public eye. Their parents have made a deliberate choice to keep the children’s lives private, which is consistent with how Chris himself was raised.
Charles’s Appearance on NCIS: Los Angeles
The main reason most people search for Charles McHugh O’Donnell is his guest appearance on NCIS: Los Angeles. In the episode “Past Lives,” which aired in 2010, Charles played a younger version of G. Callen — the same character his father portrays as an adult on the show.
Charles was approximately six or seven years old at the time of filming. His sister Lily also appeared in the same episode, making it a genuine family affair in front of the camera.
It’s a detail that fans often find charming in hindsight. The real son of the actor playing a character was cast to portray that same character as a child. Whether it was a spontaneous idea or a deliberate creative choice isn’t publicly documented, but the result is a credit that connects the O’Donnell family directly to the show in a tangible way.
According to available records, this remains Charles’s only confirmed on-screen credit. There are no other documented film or television roles attributed to him. He does not appear to have pursued acting as a continuing activity after that childhood appearance.
What We Don’t Know — and Why That’s Worth Noting
When readers look up Charles McHugh O’Donnell, they sometimes expect to find the same level of detail that exists for his father. That information simply isn’t there, and it’s important to be straightforward about that.
There are no reliable public sources documenting Charles’s schooling, hobbies, career plans, or personal relationships. No verified interviews, no solo press coverage, and no public social media accounts have been confirmed as belonging to him.
This isn’t a gap in reporting. It reflects a family that has intentionally kept their children away from the spotlight. That’s a common approach among some celebrity parents — particularly those who, like Chris O’Donnell, grew up with traditional family values and want to give their kids as normal a life as possible.
Charles is similar in this way to children of other well-known public figures — politicians, executives, or longtime entertainers — whose names are on record and who appear at public events, but whose personal lives are genuinely private. There’s nothing hidden or mysterious about it. The family has simply chosen not to make him a public figure, and that choice should be respected rather than worked around with speculation.

Final Thoughts
Charles McHugh O’Donnell is, by most measures, a private individual who happens to have a famous father and one notable childhood acting credit. His appearance in NCIS: Los Angeles as the young version of his dad’s character is a genuinely interesting footnote for fans of the show.

If you came here looking for more, the honest answer is that there isn’t more to find right now. What is known is straightforward: he’s one of five children in a close-knit family, he had a brief moment on screen as a kid, and the rest of his story is his own.
