Honestly, it’s hard to believe it’s been over a decade since The SpongeBob Movie: Sponge Out of Water hit theaters. Back in 2015, the hype was massive. People weren't just excited because it was a sequel; they were curious how the transition from 2D animation to 3D CGI "real world" visuals would actually look. It was a big risk for Nickelodeon and Paramount. But what really anchored the whole psychedelic, time-traveling mess was the voice talent. The cast of SpongeBob Movie 2015 is a fascinating mix of the legendary original voice actors who have lived in these characters since 1999 and a high-profile Hollywood heavy hitter playing the villain.
It worked. The film pulled in over $325 million globally. Why? Because while the visuals changed, the voices stayed exactly where they belonged.
The Core Bikini Bottom Residents
If you’ve watched even five minutes of the show, you know Tom Kenny. He is SpongeBob SquarePants. In the 2015 film, Kenny had to do some heavy lifting, especially when SpongeBob becomes the "Invincibubble." What’s cool about Kenny is that he doesn’t just do the voice; he manages the specific, frantic energy that makes the character work in a feature-length format without becoming annoying. He also voiced Gary the Snail, as usual.
Then you have Bill Fagerbakke as Patrick Star. Fagerbakke has this incredible ability to make Patrick sound genuinely dim-witted but incredibly lovable. In Sponge Out of Water, his transformation into "Mr. Superawesomeness" (the one who can summon ice cream) gave him some of the best lines in the script.
The rest of the main crew returned in full force too:

- Clancy Brown as Mr. Krabs (Sir Pinch-a-Lot). Brown is a veteran actor you might know from The Shawshank Redemption or Dexter: New Blood, but for millions, he’s just the world’s cheapest crab.
- Rodger Bumpass as Squidward Tentacles (Sour Note). Bumpass brings that specific nasal misery that makes Squidward the most relatable character for adults.
- Carolyn Lawrence as Sandy Cheeks (The Rodent).
- Mr. Lawrence (Doug Lawrence) as Plankton. He’s arguably the co-protagonist of this specific movie, and his chemistry with Tom Kenny’s SpongeBob is what drives the whole "Teamwork" subplot.
Antonio Banderas as Burger Beard the Pirate
This was the wildcard. Most animated movies shove a bunch of celebrities into the voice cast just for the marketing "bump." But Antonio Banderas wasn't just a voice. He was the primary live-action presence. Playing Burger Beard, Banderas went full "panto" villain. He was campy, he was dirty, and he looked like he was having the time of his life on that pirate ship.
Banderas's character is the one who steals the secret formula using a magical book that makes whatever he writes come true. It’s a meta-narrative device that allowed the writers to break the fourth wall. Having an actor of Banderas’s caliber—someone who can do Puss in Boots and then turn around and do a Pedro Almodóvar film—added a layer of "prestige" silliness that the movie needed to bridge the gap between the 2D ocean and the 3D beach.
The Surprising Cameos and Support
Matt Berry. If you know What We Do in the Shadows or The IT Crowd, you know that voice. He played Bubbles, the magical dolphin who watches over the cosmos. It is one of the weirdest parts of the movie. Seriously. A dolphin that shoots lasers from its blowhole while sounding like a Shakespearean actor? That’s pure Matt Berry.
We also got the "Seagulls." These were voiced by a variety of people, including some familiar names:

- Tim Conway (a comedy legend who also voiced Barnacle Boy in the series).
- Eddie Deezen (the quintessential "nerd" voice from Grease and Dexter’s Laboratory).
- Rob Paulsen (the man behind Pinky from Pinky and the Brain).
- Billy West (Fry from Futurama).
It’s a bit of a "Who's Who" of voice acting royalty. They weren't just hiring random people; they were hiring the best in the business to play talking birds. Even Jill Talley, Tom Kenny’s real-life wife, returned as Karen, Plankton’s computer wife. It’s a tight-knit group.
Why the Voice Acting Mattered for the 3D Transition
There was a lot of skepticism about the "superhero" versions of these characters. When the trailers first dropped showing SpongeBob with massive traps and a cape, people were worried it would lose its soul. But because the cast of SpongeBob Movie 2015 stayed consistent, the "soul" remained.
You can change the textures. You can give Patrick six-pack abs made of ice cream. But as long as that Bill Fagerbakke chuckle is there, the audience stays connected. This is a lesson many modern reboots fail to learn. They swap out the voice cast for "bigger names" and lose the essence of the characters in the process. Sponge Out of Water didn't do that. It respected the source material while letting the actors play with a bigger budget.
Behind the Mic: The Recording Process
Most people think voice actors just stand in a booth alone. While that happens a lot, the SpongeBob cast often records together when possible. This helps with the comedic timing. You can’t fake the back-and-forth banter between SpongeBob and Plankton if the actors aren't feeding off each other's energy.

During the 2015 production, the cast had to adapt to the "live action" integration. When Antonio Banderas was filming on a physical ship in Savannah, Georgia, he wasn't always acting against nothing. Sometimes they had stand-ins or puppets, but the voice work had to be layered in perfectly to match his over-the-top performance. It’s a technical nightmare that the editors and actors made look effortless.
Actionable Takeaways for Fans and Collectors
If you're looking to dive deeper into the world of the 2015 film or just want to appreciate the work of this cast, here is what you should actually do:
- Watch the "Making Of" Featurettes: Specifically look for the "Behind the Scenes" clips on the Blu-ray or YouTube. Seeing Matt Berry record the lines for Bubbles the Dolphin is a masterclass in voice acting.
- Listen to the Soundtrack: People forget that N.E.R.D (Pharrell Williams' group) did songs for this movie. The way the voice cast's energy meshes with Pharrell's production is pretty unique for a "kids' movie."
- Check out 'The SpongeBob Musical': If you like the character dynamics in the 2015 film, look into the Broadway musical. While it uses different actors, it captures that same "live-action meets cartoon" energy that the 2015 movie pioneered.
- Follow the Voice Actors on Social Media: Tom Kenny and Rob Paulsen are frequent guests on voice-acting podcasts (like Talkin' Toons). They often share specific anecdotes about the 2015 recording sessions that didn't make it into the official PR materials.
The 2015 film remains a high point for the franchise because it didn't try to "fix" what wasn't broken. It took the most talented people in the industry, gave them a weird script about a magical book and a time-traveling dolphin, and let them cook. Whether you're a parent watching it for the fiftieth time or a casual fan of animation, the vocal performances are what keep the movie from sinking to the bottom of the sea.
