You remember the scene. Zach Galifianakis is standing on a hotel balcony in Las Vegas, wearing an absurdly small baby carrier, sunglasses, and a look of total bewilderment. Strapped to his chest is a baby he calls "Carlos." It became the defining image of 2009's The Hangover. Honestly, that one visual probably sold more tickets than the entire theatrical trailer. People were obsessed. They wanted to know who the kid was, if he was actually safe during those chaotic stunts, and whatever happened to the Hangover movie Carlos after the credits rolled and the Wolfpack went home.
It's funny how a baby with zero lines can become a global icon. Carlos wasn't even his real name—it was Tyler. But "Carlos" stuck. It’s one of those rare moments in pop culture where a literal infant steals the spotlight from established comedic heavyweights like Bradley Cooper and Ed Helms.
The Secret Identity of the Hangover Movie Carlos
The baby wasn't played by just one person. In Hollywood, infant labor laws are incredibly strict, so productions almost always hire twins or a rotation of babies to ensure nobody gets overworked or cranky on set. For the role of Tyler (aka Carlos), the production primarily used a set of twins: Grant and Avery Holmquist.
Most of the screen time, particularly the iconic shots where "Carlos" is mimicking Alan's mannerisms, featured Grant Holmquist. He was only about six months old at the time. Can you imagine? You’re barely crawling and you’re already part of the highest-grossing R-rated comedy of its era.
There's a persistent myth that the baby in the movie belonged to someone on the crew. Not true. The Holmquist twins went through a standard casting process. Their mother, Carrie Holmquist, is a photographer, which probably helped with the kids being comfortable around cameras and bright lights. But Grant was the standout. He had this specific, deadpan expression that matched Zach Galifianakis’s energy perfectly. It wasn't just luck; it was a weirdly perfect comedic chemistry between a grown man and a six-month-old.
What Actually Happened on That Set?
Let’s talk about the logistics because sticking a baby in a movie about roofies, tigers, and Mike Tyson sounds like a nightmare for a legal department. It was.
Director Todd Phillips has mentioned in various interviews that they had to be extremely careful. Whenever you see the baby in a "dangerous" situation—like the infamous scene where a car door nearly hits him or the "jacking off" gesture joke—the baby wasn't actually there for the risky part.

Modern audiences sometimes forget that The Hangover used a mix of real babies and very lifelike dummies. If the action was too loud or the movement too sudden, they swapped Grant out for a high-end prop. That "Carlos" jacking off joke? That was a mechanical arm and a prosthetic. Obviously. But the seamless editing made it look like the kid was just naturally gifted at raunchy physical comedy.
The cast actually bonded with the twins. Zach Galifianakis, despite his screen persona as a socially inept man-child, was reportedly very gentle and great with the kids. He had to be; he spent hours with a baby literally strapped to his torso. If the baby didn't trust him, the shoot would have stalled for days.
The Return of the Wolfpack’s Smallest Member
Most child actors from massive blockbusters disappear into the "Where are they now?" void of the internet. That almost happened here. But then, The Hangover Part III went into production in 2013.
The writers wanted a full-circle moment. They reached out to the Holmquist family to see if Grant could return. By this time, Grant was about six years old. He actually had to audition again. Todd Phillips wanted to make sure he still had that "look." He did. Seeing a grown-up Grant Holmquist interact with Alan one more time gave the trilogy a weirdly emotional anchor that the second movie lacked.
It's rare for a franchise to keep the same baby actor for the sequel years later. Usually, they just cast whoever looks the right age. But the fans' connection to the Hangover movie Carlos was so specific that bringing Grant back felt like a necessary nod to the original's magic.
Why We Are Still Obsessed With This Character
Why does a baby in a carrier still generate searches and memes fifteen years later? It’s the contrast.

The "Wolfpack" represents the absolute worst of adult behavior. They are messy, hungover, unethical, and desperate. Dropping an innocent, silent, sunglass-wearing baby into the middle of that Vegas carnage creates an immediate comedic tension. He is the "straight man" in a world of clowns.
Also, Carlos represents the mystery of the "missing night." For the first half of the film, we don't know where he came from. He is a living, breathing clue that the characters—and the audience—have to solve. He’s not just a prop; he’s the physical manifestation of how badly they messed up.
Life After the Fedora: Where is Grant Holmquist Now?
Grant isn't a child star in the traditional sense. He didn't chase the Hollywood dream after the trilogy wrapped. According to his mother’s social media updates over the years, he’s lived a relatively normal life.
He’s a teenager now. Think about that. The baby from the carrier is likely navigating high school, probably getting tagged in "Carlos" memes by his friends every single week. He’s mostly stayed out of the spotlight, which is probably the healthiest move a former child star can make. Occasionally, photos surface of him at fan conventions or anniversaries, and he still carries a bit of that "Carlos" charm, though he’s traded the baby carrier for a normal life.
The Legacy of the Baby in the Carrier
The Hangover movie Carlos changed how comedies use kids. Before 2009, babies in comedies were usually there to be "cute" or to cause "stinky diaper" problems. Carlos was different. He was treated like a member of the gang. He wore the shades. He sat at the breakfast table while they discussed hookers and missing teeth.
He became a costume staple. Walk into any Halloween party even today, and there's a 50% chance you'll see a guy with a beard and a fake baby strapped to his chest. That is staying power.

Key Takeaways for Fans of the Film
If you're looking to dive deeper into the lore of the film or perhaps trying to recreate the look for a party, keep these facts in your back pocket:
- The Actor: Grant Holmquist is the primary actor, though his twin sister Avery was also on set.
- The "Carlos" Name: It was an ad-lib by Zach Galifianakis. The character's name in the script was Tyler, the son of Jade (Heather Graham).
- Safety First: The "stunt" baby was often a high-quality silicone doll, especially in scenes involving the tiger or the police station.
- The Reunion: Grant is the only actor to play the "same" child character in both the first and third films, a rare feat in cinema.
Watching The Hangover today, the Carlos scenes still hold up. They don't feel dated like some of the other humor in the movie might. There is something timeless about a baby who just doesn't give a damn about the chaos surrounding him. He was the calmest person in Las Vegas, and maybe that's why we loved him.
If you're revisiting the franchise, pay close attention to the scene in the elevator. The way the baby tracks the movement of the actors is remarkably professional for an infant. It’s those tiny details that turned a random casting choice into a piece of cinematic history.
To understand the full impact of the film's casting, you can look into the work of Janet Hirshenson and Jane Jenkins, the casting directors who found the twins. They were looking for "a baby that could look at Zach and not cry," and in Grant Holmquist, they found a legend.
The next time you see a guy in a "Human Tree" shirt and shades, remember that there's a real kid out there who lived that movie—and he’s probably tired of people calling him Carlos.
Next Steps for Your Rewatch
To get the most out of your next Hangover viewing, focus on the continuity of the baby. You’ll notice the subtle swaps between the real Grant and the "stunt" doll. Also, check out the behind-the-scenes features on the Blu-ray; there is some gold-standard footage of Zach Galifianakis trying to keep the twins entertained between takes. It gives you a whole new appreciation for the work that goes into making a "wild" comedy look so effortless. Finally, if you're interested in child acting laws, the California Department of Industrial Relations provides the actual frameworks that the production had to follow, which explains why Carlos disappears in certain scenes where he "should" have been present.
