Yes—at least in that specific Xfinity ad, it actually is his real child. In the recent Xfinity campaign featuring Jeff Goldblum, the commercial includes cameos from his real family, including his wife and children.

What Happens in the Commercial
In the ad:
- Jeff Goldblum appears with a child playing his son
- They interact in a home setting with a “magical” theme
What makes this one different from many commercials is that:
The child shown is not just a random actor
It’s actually his real son (part of his family appearing in the ad)
Why It Feels Unclear
Even though it’s real, people still question it because:
1. Most Ads Use Actors
Normally, commercials cast child actors—not real family members.
2. Natural Chemistry
Their interaction feels natural, which can either confirm or confuse viewers.
3. Multiple Versions of Ads
Xfinity has released different commercials (like the Jurassic Park one or Wicked tie-in), and not all feature his real family.
Important Detail
Not every Xfinity ad with Jeff Goldblum includes his real son.
- Some ads → only actors
- This specific “family-style” ad → includes his real kids
So the answer depends on which commercial you’re watching.
Final Thoughts
Yes, in that Xfinity commercial, the child with Jeff Goldblum is his real son. The campaign intentionally included his real family to make the story feel more personal and authentic.
That’s why it feels so natural—it actually is.
