You’ve seen it on social media. You’ve probably seen it in those weirdly specific celebrity "fact" threads that pop up at 2:00 AM. The rumor that Blair Underwood has a twin brother is one of those Hollywood myths that just won't stay buried. It’s persistent. It’s everywhere. But honestly? It’s completely wrong.
Let’s get the big one out of the way immediately. Blair Underwood does not have a twin brother. It’s kind of wild how these things start. Someone sees a photo of a sibling, notes a strong family resemblance, and suddenly the internet has decided they were born five minutes apart. In reality, while the L.A. Law and Sex and the City star comes from a close-knit, high-achieving family, his "twin" is actually his older brother, Frank Underwood Jr.
The "Twin" Confusion Explained
If you look at photos of Blair and Frank Jr. together—especially from their younger days or at red-carpet events like the premiere of A Streetcar Named Desire—it’s easy to see why a casual observer might trip up. They have that same structured jawline and the signature Underwood smile.
But Frank Jr. is the older brother. He isn't a twin.
The two have actually worked together quite a bit. Back in the early 90s, they teamed up for a short film called The Second Coming. It was a pretty bold project for the time, with Blair playing a Christ-like figure and Frank Jr. involved in the production side. They even formed a production company together called Eclectic Entertainment.

People often mistake creative partners for twins when they share a last name and a face, but their birth certificates definitely have different years on them.
Who is Frank Underwood Jr.?
Frank Jr. isn't just "the brother." He’s a legitimate talent in his own right, though he tends to stay more behind the scenes than Blair. He’s an artist, an author, and a producer. While Blair was busy becoming a household name on L.A. Law, Frank Jr. was carving out a space in the world of visual arts and literature.
Their father, Colonel Frank Underwood Sr., was a big influence on both of them. Growing up as "Army brats," the siblings moved around a lot—from Tacoma, Washington, to various bases around the world. That kind of lifestyle usually does one of two things: it either drives siblings apart or makes them incredibly tight. For the Underwoods, it was the latter.
The Rest of the Underwood Clan
It isn't just the two of them, either. The Underwood family is actually a bit bigger than most people realize. Blair has two sisters:

When you look at the whole family tree, you see a pattern of discipline and creativity. Their mom, Marilyn Ann Scales, was an interior decorator, which probably explains where the artistic streak comes from. Between an Army Colonel father and an interior designer mother, you’ve got a mix of rigid structure and total creative freedom.
Why the Twin Myth Persists
Why does the "Blair Underwood twin brother" search query keep trending?
Part of it is just the nature of celebrity. People love a "secret sibling" story. There’s also a bit of confusion with other actors. For example, some fans occasionally mix up Blair Underwood with actors like Sam Underwood (who actually did play twins on the show The Following) or other performers with similar names.
Plus, there’s the House of Cards effect. Because the lead character in that show was named Frank Underwood, and Blair’s brother and father are both named Frank Underwood, the SEO algorithms of the world occasionally have a meltdown. If you Google "Frank Underwood," you’re more likely to see Kevin Spacey’s face than Blair’s brother, which just adds more layers to the confusion.

The Real Story is Better Than the Myth
Honestly, the reality of Blair’s family is more interesting than a made-up twin story. You have a family that transitioned from military life to the heights of Hollywood and the arts without the typical "child star" meltdowns or public feuds.
Blair has often credited his family—especially his brother Frank Jr.—for keeping him grounded. When he was nominated for Golden Globes or winning NAACP Image Awards, he wasn't off in a Hollywood bubble. He was working with his brother, leaning on his sisters, and visiting his parents in Virginia.
Setting the Record Straight
If you’re looking for the "secret twin," you won't find him. What you will find is a set of siblings who have supported each other’s careers for over four decades.
Next time someone tells you about Blair Underwood’s twin, you can tell them the truth:
- Frank Jr. is the older brother, not a twin.
- They are business partners who ran a production company together.
- The family resemblance is just really, really strong.
If you want to see their chemistry for yourself, it’s worth digging up old interviews from the 90s where they talk about their production work. You can see the mutual respect there. It’s not a "twin connection"—it’s just a solid brotherhood.
