Finding Nemo came out in 2003 and basically changed how we look at the ocean forever. It was a massive hit. But honestly, the standout wasn't just the orange clownfish looking for his son; it was the blue tang with the memory problems. When Pixar finally got around to the sequel over a decade later, everyone had one major question: who voiced Dory in Finding Dory and would they bring back that same magic?
The answer is, of course, Ellen DeGeneres.

It’s hard to imagine anyone else doing it. Seriously. Ellen didn't just read lines in a booth; she defined the cadence, the stuttering optimism, and the "just keep swimming" mantra that eventually became a global phenomenon. By the time 2016 rolled around for the release of Finding Dory, Ellen had spent years jokingly lobbying for a sequel on her talk show. It became a bit. A long, multi-year bit that actually worked.
The Ellen Factor: More Than Just a Voice
When you think about the voice of Dory, you’re thinking about Ellen’s specific brand of observational humor. Pixar didn't just hire a celebrity for the marquee value. They hired a personality. Director Andrew Stanton has been on record multiple times saying that he specifically wrote the character for her after seeing her on her sitcom, Ellen, where she would often trail off or get distracted in the middle of a sentence.
That "Dory-ness" was already there.
In Finding Dory, the stakes were higher than the first film. We weren't just looking for a lost fish; we were looking for Dory's parents, Jenny and Charlie. This required a level of emotional depth that went beyond the "I forgot what I was saying" jokes. Ellen had to balance the character's signature flightiness with genuine, heart-wrenching anxiety. It’s a performance that grounds a movie about talking fish in very real human emotions like the fear of abandonment and the struggle with a disability.
The Rest of the Reef: Who Else Was in the Booth?
While Ellen is the face—or the voice—of the franchise, the casting for Finding Dory was stacked with heavy hitters. You can't talk about who voiced Dory in Finding Dory without mentioning the younger versions of her. Because the movie jumps back into her childhood, we actually get a few different "Dorys."
- Sloane Murray voiced the toddler version (Baby Dory). If you remember the "I suffer from short-term memory loss" line that went viral on TikTok and Instagram, that was her.
- Lucia Geddes provided the voice for Dory as a "tween" or teenager in the flashback sequences.
Then you have the supporting cast. Ty Burrell, famous for Modern Family, played Bailey the beluga whale. Kaitlin Olson brought a hilarious, near-sighted energy to Destiny the whale shark. And we can't forget Ed O'Neill as Hank the "septopus." The chemistry between Ellen’s frantic energy and Ed O’Neill’s grumpiness is basically the engine that drives the middle of the movie. It’s a classic odd-couple pairing, but with more suction cups.
Why Casting Matters for SEO and Legacy
People often search for who voiced Dory in Finding Dory because the voice feels so familiar, yet so distinct from Ellen's daily talk-show persona. In the world of animation, "celebrity casting" is often criticized. People think studios just want big names to put on posters. But with Dory, it was different.
This wasn't a stunt.
It was a perfect alignment of a performer's natural speech patterns and a character's internal struggle. If you swap Ellen out, the movie fails. It’s that simple. Her voice has a specific "breathiness" and a tendency to jump in pitch when she's excited, which perfectly mimics the darting movements of a blue tang in a coral reef.
The Technical Side of Being a Blue Tang
Recording an animated feature isn't like filming a live-action movie. Ellen wasn't in the room with Albert Brooks (who voiced Marlin) or Hayden Rolence (who took over as Nemo for the sequel). Most of the time, voice actors are alone in a padded room, wearing headphones, reacting to nothing.
Stanton would feed her lines, and Ellen would riff.
That’s where the "whale speak" came from. It wasn't strictly scripted to sound exactly like that; it was an improvisation that became iconic. To voice a character like Dory, you have to be comfortable looking a little silly. You have to make weird noises into a high-end microphone while a bunch of producers watch you from behind a glass pane.

Little Known Facts About the Casting
- Hayden Rolence replaced Alexander Gould. In the original Finding Nemo, Alexander Gould voiced the titular character. But since fish don't age at the same rate as human boys, Gould's voice had dropped significantly by 2016. He actually has a small cameo in Finding Dory as a truck driver named Carl, but Hayden Rolence stepped in to keep Nemo sounding like a kid.
- Sigourney Weaver played herself. One of the funniest running gags in the movie is Dory believing Sigourney Weaver is her personal friend because she hears her voice over the intercom at the Marine Life Institute. Sigourney actually recorded those lines specifically for the film.
- Idris Elba and Dominic West. For fans of The Wire, seeing (or hearing) these two together as the sea lions Fluke and Rudder was a massive "Easter Egg."
The Emotional Impact of the Voice
Dory represents something specific: the idea that "different" isn't "broken." When Ellen voices those moments where Dory feels like a burden to Marlin or Nemo, you can hear the crack in her voice. It's subtle. It's not melodramatic. It's just a small, quiet realization of inadequacy.
That is why the casting worked.
The movie grossed over $1 billion worldwide. People didn't just go for the colors or the Pixar brand; they went because they were invested in Dory’s journey. They wanted to see her find her parents, but more importantly, they wanted to see her find her confidence.
Actionable Takeaways for Movie Buffs
If you're looking to dive deeper into the world of Pixar's casting or the making of this specific film, there are a few things you can do to see the "behind the scenes" magic.
- Watch the "Behind the Mic" featurettes. Disney+ has a whole section for Finding Dory extras. Watching Ellen in the recording booth reveals how much physical energy she puts into the role. She’s not just standing there; she’s moving her whole body to get the right sound.
- Compare the original to the sequel. If you listen closely to Finding Nemo and then Finding Dory, you can hear how Ellen’s portrayal evolved. In the first film, she’s a sidekick. In the second, she’s the lead, and her voice carries a much heavier emotional load.
- Check out the "Whale Speak" origins. There are several interviews where the sound designers explain how they layered Ellen's voice with actual underwater acoustic effects to make the whale speak sound "authentic" yet hilarious.
The legacy of who voiced Dory in Finding Dory is ultimately about a perfect match between actor and character. Ellen DeGeneres gave Dory a soul, a memory (or lack thereof), and a heart that resonated with millions of people who also feel a little lost sometimes.
To truly appreciate the performance, re-watch the scene where Dory is alone in the shipping pipes. The way her voice echoes and the panic in her tone—that's masterclass voice acting. It’s not just about being funny; it’s about being real in a world made of pixels.
Next time you’re watching, pay attention to the silence. Some of the best parts of Ellen's performance aren't the jokes, but the quiet gasps and the soft "oh"s when Dory realizes she's forgotten something important again. That's the nuance that made the character a legend.
