When DreamWorks dropped The Croods back in 2013, nobody really expected a movie about a bunch of dirty, terrified cave-dwellers to become a massive franchise. But it did. Honestly, the magic isn't just in the vibrant, neon-colored prehistoric flora; it's the chemistry. The cast of the Croods family tree is a weirdly perfect mix of Hollywood A-listers, quirky character actors, and legendary comedians who somehow make a "family of six and a guy they found in the woods" feel like your own chaotic Sunday dinner.
You’ve got the overprotective dad, the rebellious teen, and the grandmother who refuses to die just to spite her son-in-law. It's a classic sitcom dynamic, just set in the "Croodaceous" era. But if you look at the names behind the voices—Nicolas Cage, Emma Stone, Ryan Reynolds—you realize this wasn't just a small project. It was a powerhouse production that managed to span two feature films and multiple TV spin-offs.
Breaking Down the Core Family Tree
Let's look at the roots. Grug Crood is the patriarch. He’s voiced by Nicolas Cage, who brings that trademark intensity to a man whose entire personality is built on "fear is good, change is bad." Cage doesn't just read lines; he grunts and bellows with a sincerity that makes you actually feel for a guy who thinks a cave is the peak of architectural design. Grug’s wife, Ugga, is the glue. She’s voiced by Catherine Keener. While Grug is the brawn (and the anxiety), Ugga is the one actually keeping the kids alive. Keener plays her with this grounded, weary warmth that balances out Cage's high-energy panic.
Then there’s Eep. She's the catalyst for the whole story. Emma Stone voices her with that raspy, energetic charm we saw in her early career. Eep is the eldest daughter, the one who wants to "see the sun," which basically means she’s a metaphor for every teenager who ever wanted to move out of their parents' basement. The family tree gets a bit more crowded with Thunk, the middle child. Clark Duke provides the voice here, playing Thunk as a lovable, somewhat dim-witted kid who just wants his dad's approval.
And we can’t forget the baby, Sandy. Originally, she was voiced by Randy Thom, who is actually a legendary sound designer. Sandy doesn’t speak much; she growls and bites. She’s basically a feral terrier in a loincloth.
The Outliers and In-Laws
The tree wouldn't be complete without Gran. Cloris Leachman voiced her in both films, and honestly, she stole every scene she was in. Gran is Ugga’s mother and Grug’s literal nightmare. The running gag of Grug checking to see if she’s still alive is dark, sure, but Leachman’s delivery made it hilarious.

Then enters Guy. He’s not a Crood by blood, but he’s the branch that changes the whole tree’s direction. Ryan Reynolds voices Guy. He brings that fast-talking, slightly arrogant but ultimately well-meaning "New Age" vibe. Guy is the one who introduces the concept of "ideas" to a family that previously thought a rock was a high-tech tool. Guy also brings Belt, his pet sloth, voiced by Chris Sanders (who actually co-directed the first film). Belt doesn't say much besides "Da-da-daaa!", but he's iconic.
How the Cast Changed for the Sequel and Beyond
When The Croods: A New Age hit theaters in 2020, the cast of the Croods family tree expanded. We met the Bettermans. They’re the "evolved" foils to the Croods. Peter Dinklage plays Phil Betterman, the passive-aggressive, man-bun-wearing architect of a walled-in paradise. Leslie Mann voices his wife, Hope, and Kelly Marie Tran plays their daughter, Dawn.
Adding the Bettermans was a smart move. It forced the Croods to look at themselves through a modern lens. Peter Dinklage is particularly great here—he uses that sophisticated, slightly condescending tone he perfected in Game of Thrones but applies it to prehistoric organic farming. It’s a weirdly specific vibe that works.
The Small Screen Transition
Here’s where it gets tricky. If you’ve watched Dawn of the Croods on Netflix or The Croods: Family Tree on Hulu/Peacock, you might have noticed the voices sound... different. That’s because the A-list movie stars didn't stick around for the TV shows.
- Dan Milano took over for Nicolas Cage as Grug.
- Stephanie Lemelin replaced Emma Stone as Eep.
- A.J. Locascio stepped in for Ryan Reynolds as Guy.
- Artemis Pebdani took over the legendary role of Gran from Cloris Leachman.
It's a common move in the industry. Big stars are expensive and busy. The TV cast does a phenomenal job of mimicking the cadences of the original actors while making the roles their own. If you’re a parent who has had these shows on loop for 400 hours, you probably don't even notice the difference anymore. You’ve just accepted Dan Milano as the voice of caveman anxiety.

Why This Specific Cast Worked So Well
There’s a nuance to voice acting that people often overlook. You can't just throw famous people in a booth and expect a hit. Look at Shark Tale—huge stars, but the movie felt like a corporate board meeting. The Croods felt different.
The chemistry between Cage and Reynolds is the secret sauce. Cage’s Grug is slow, heavy, and loud. Reynolds’ Guy is quick, light, and clever. Their vocal contrast creates a natural comedic friction. Then you add Emma Stone’s Eep, who acts as the bridge between the old world and the new. It’s a trio that anchors the entire emotional arc of the franchise.
Fun Fact: The Sloth Connection
Did you know Chris Sanders, the voice of Belt, also voiced Stitch in Lilo & Stitch? He’s also the guy who co-wrote and directed How to Train Your Dragon. The man has a literal Midas touch when it comes to quirky sidekicks. Belt’s signature "Dun dun duuuun" wasn't even in the original script—it was something they played around with in the booth that ended up becoming a series staple.
The Evolutionary Journey of the Characters
The cast of the Croods family tree isn't static. By the time we get to the TV series The Croods: Family Tree, the family has basically merged with the Bettermans. We see more of Dawn and Eep's friendship, which is a refreshing break from the usual "jealous girls" trope. They call themselves the "Thunder Sisters," a callback to a joke in the second movie that became a fan favorite.
This evolution is important. If the characters stayed stuck in their ways, the franchise would have died out after the first film. Instead, we see Grug slowly—very slowly—learning to trust Guy. We see Ugga finding her own voice outside of just being a mother. We see Thunk discover... well, "window" (the prehistoric version of TV).

Practical Takeaways for Fans and Collectors
If you're a die-hard fan looking to dive deeper into the world of the Croods, there are a few things you should know.
- Check the Credits: If you're watching the TV shows, don't go looking for Ryan Reynolds' name. He’s not there. But the voice actors who are there have been doing this for years and often have incredible backgrounds in legendary shows like Adventure Time or Voltron.
- The Soundtrack Matters: Alan Silvestri did the score for the first movie. Yes, the guy who did Avengers and Back to the Future. It’s part of why the first film feels so epic.
- The Art Books: If you can find a copy of The Art of the Croods, grab it. It shows how the character designs were built to match the personalities of the cast. Eep’s design, for instance, was heavily influenced by the need for her to look like a powerhouse athlete, not a typical "princess."
The legacy of The Croods is surprisingly sturdy. It’s a story about the end of the world—literally—and how a family survives it by sticking together. Whether it’s Nicolas Cage screaming at the sun or Peter Dinklage bragging about his "man cave," the cast has turned a simple concept into a decade-long staple of animation.
If you're looking to rewatch, start with the 2013 original to appreciate the Cage/Stone/Reynolds dynamic. Then, move to the 2020 sequel to see how the Bettermans shake things up. Only then should you dive into the Hulu/Peacock series The Croods: Family Tree to see how the next generation of voice actors carries the torch. You'll find that while the voices might change, the heart of the "Croodaceous" family stays exactly the same.
To stay updated on future releases or potential third films, follow the official DreamWorks Animation social channels. They often post behind-the-scenes clips of the voice actors in the booth, which is the best way to see the "human" side of these prehistoric characters. You can also track the cast's other projects; for instance, Kelly Marie Tran has become a huge name in the voice acting world after her success in Raya and the Last Dragon. Watching how these actors move between different animated worlds gives you a much better appreciation for the skill it takes to bring a drawing to life.
