Finding Dory was one of those rare sequels that actually felt like it had a reason to exist. It wasn't just a cash grab. It was a character study disguised as a colorful fish movie. But honestly, when you watch it, you spend half the time squinting at the screen trying to figure out why the octopus sounds so familiar. The finding dory movie cast is a weirdly specific mix of sitcom legends, prestige TV actors, and SNL alumni that shouldn't work together, but totally does.
Pixar has this habit of casting for "vibe" rather than just star power. Sure, they have big names, but they often choose people whose natural speaking cadence fits the frantic energy of a neurotic reef fish or a grumpy septopus.
The Anchors: Ellen DeGeneres and Albert Brooks
It’s impossible to talk about this film without starting with Ellen. She basically campaigned for this movie for a decade on her talk show. Dory is a hard character to play because she could easily become annoying. The short-term memory loss gag has a shelf life of about ten minutes if you don't ground it in something real. Ellen brings this vulnerability to the role that makes you want to hug a blue tang. It's a performance built on breathy pauses and a certain kind of optimistic desperation.
Then there’s Albert Brooks as Marlin.
Brooks is a comedy architect. He’s known for playing high-anxiety intellectuals, and he brought that exact energy to a clownfish. In the first movie, he was the lead. Here, he’s the supporting act, and he plays the "frustrated but loving father" role with a lot of nuance. He’s the cynical foil to Dory’s "just keep swimming" philosophy. If you listen closely, his timing is impeccable—he knows exactly when to let a line trail off to show Marlin’s exhaustion.
The Scene-Stealer: Ed O'Neill as Hank
Hank is basically the best thing about the sequel. Ed O'Neill, whom most people know from Modern Family or Married... with Children, voices this "septopus." Hank is a misanthrope. He just wants to live in an enclosure in Cleveland where nobody will touch him.
O'Neill’s voice is gravelly and tired. It perfectly captures a creature that has literally given up on the ocean. The chemistry between O'Neill and DeGeneres is the engine of the movie’s second act. It’s a classic buddy-cop dynamic: the ray of sunshine meets the cloud of doom. Interestingly, O'Neill has mentioned in interviews that he didn't even realize he was the co-lead of the movie for a long time because voice acting is done in such isolated bubbles. He just kept showing up for sessions and seeing more and more lines for Hank.
The Modern Family Reunion
If you felt like the finding dory movie cast sounded a lot like an ABC Wednesday night lineup, you weren't imagining things. Pixar leaned hard into the Modern Family talent pool. Aside from Ed O'Neill, we got Ty Burrell as Bailey, the beluga whale with "broken" echolocation.

Burrell plays Bailey with the same well-meaning but slightly dim-witted energy he brings to Phil Dunphy. It’s a great comedic contrast to Kaitlin Olson’s Destiny. Olson, famous for It’s Always Sunny in Philadelphia, plays a nearsighted whale shark. Her voice has this natural rasp and frantic edge that makes Destiny feel like a real person—or, well, a real shark—struggling with a physical handicap. The back-and-forth between the beluga and the whale shark provides some of the best physical comedy in the film, even though it’s all digital.
Idris Elba and Dominic West: The Wire at Sea
This is the one that usually shocks people.
The two sea lions, Fluke and Rudder, who spend their days lounging on a rock and bullying a third sea lion named Gerald? Those are voiced by Idris Elba and Dominic West.
Yes, Stringer Bell and Jimmy McNulty from The Wire.
It’s a massive inside joke for TV nerds. Seeing these two powerhouse dramatic actors play lazy, territorial pinnipeds is hilarious. They use their natural British accents (well, West is British, and Elba is... Elba), which gives the sea lions a weirdly sophisticated yet thuggish vibe. They sound like retired gangsters who just want to sunbathe in peace. When they shout "Off! Off! Off!" at Gerald, it’s coming from the same voices that defined one of the grittiest dramas in television history.
The Voices Behind the Parents
Flashbacks are a huge part of Dory’s journey, which meant Pixar had to find the right voices for Charlie and Jenny, Dory’s parents. They landed on Eugene Levy and Diane Keaton.
Think about that for a second.

Levy brings that gentle, supportive "dad" energy that he later perfected in Schitt's Creek. He’s patient and kind. Keaton brings her trademark nervous energy and warmth. They make the stakes of the movie feel personal. When you hear them calling out for "Dory," you aren't just hearing voice actors; you're hearing the sound of a family that’s been incomplete for years. It adds a layer of weight to the movie that prevents it from being just another "lost and found" story.
Sigourney Weaver as... Sigourney Weaver
One of the most bizarre and brilliant casting choices in the finding dory movie cast isn't even a character in the traditional sense. Throughout the Marine Life Institute, the "Voice of the Institute" is Sigourney Weaver.
She’s playing herself.
In the world of the movie, she’s the celebrity spokesperson for the aquarium. Every time Dory hears her voice over the speakers, she says, "My friend Sigourney Weaver," as if they’re on a first-name basis. It’s a meta-joke that works because Weaver is so associated with nature documentaries and science fiction. It’s a dry, witty touch that rewards the adults in the audience without confusing the kids.
The Supporting Players and Cameos
The depth of this cast goes even further if you look at the smaller roles:
- Bill Hader and Maya Rudolph: They have a brief cameo as a couple of fish that Dory encounters early on. It’s a classic SNL pairing.
- Bob Peterson: He’s a Pixar veteran who returns as Mr. Ray, the schoolteacher stingray. He also voiced Roz in Monsters, Inc. and Dug in Up.
- Andrew Stanton: The director himself voices Crush, the sea turtle. He’s been playing that dude-bro turtle since 2003, and honestly, no one else could do it better.
- Sloane Murray: She provided the voice for Baby Dory. Those "pip-squeak" lines became an instant internet sensation because they were genuinely adorable, not manufactured "cute."
Why the Casting Matters for SEO and Discovery
When people search for the finding dory movie cast, they usually want to confirm a "Wait, is that...?" moment. They recognized a voice but couldn't place the face. By mixing prestige actors like Elba with comedy staples like Levy and O'Neill, Pixar created a vocal texture that feels rich.
It’s also worth noting that the cast changed from the first movie. In Finding Nemo, the character of Nemo was voiced by Alexander Gould. By the time the sequel happened thirteen years later, Gould’s voice had dropped significantly—he was an adult. So, Pixar cast Hayden Rolence to play Nemo, though they gave Gould a small cameo as a truck driver at the end of the film as a nod to the original fans.

Nuance in Voice Acting
A lot of people think voice acting is just talking into a mic. It's not.
Take the character of Becky, the loon. She doesn't have "lines" in the traditional sense, but the vocalizations require a specific kind of performance to convey intelligence (or a lack thereof) without words. Or look at the contrast between the various "types" of voices: you have the sharp, staccato delivery of the crabs and the flowing, melodic tones of the turtles.
The casting directors, Kevin Reher and Natalie Lyon, deserve a lot of credit for not just picking the most famous people available. They picked voices that contrast well. You never confuse Hank for Marlin, or Destiny for Dory, because the "vocal silhouettes" are so distinct.
Actionable Insights for Your Next Rewatch
If you’re planning on sitting down with the family to watch Dory again, here are a few things to keep an ear out for to make it more interesting:
- Listen for the "Wire" Reunion: Next time the sea lions are on screen, try to imagine them in Baltimore. It changes the whole vibe of the "Off! Off!" scene.
- Identify the Cameros: See if you can spot Bill Hader’s distinct delivery before he gets scared off by Dory.
- Track the Evolution of Nemo: Compare Hayden Rolence’s performance to the original. He does a remarkable job of mimicking the cadence of a young Alexander Gould while bringing his own energy to the role.
- Appreciate the Sound Design: Notice how the voices change when the characters are in the pipes versus the open ocean. The "muffled" quality of the voices in the Marine Life Institute’s plumbing adds a lot of realism to the performances.
Finding Dory works because the cast treats the material with respect. They don't "act for kids." They play the emotions straight. Whether it's Ed O'Neill's grumpy reluctance or Ellen's frantic hope, the performances are what turn a movie about fish into a story about the meaning of home. It’s a masterclass in ensemble voice casting that holds up years after its release.
