Let’s be honest. When Madagascar first hit theaters back in 2005, nobody expected the sidekicks to steal the entire franchise. But they did. Those four flightless birds—Skipper, Kowalski, Rico, and Private—basically hijacked the screen with a mix of military precision and total absurdity. It wasn’t just the writing, though. It was the voices. The cast of the Penguins of Madagascar is one of those rare instances where a studio transitioned from "celebrity stunt casting" to "perfect character fit" without losing any of the magic.
Most people don't realize that the voice cast actually shifted quite a bit between the original movies, the Nickelodeon TV series, and the 2014 standalone film. It’s a bit of a rabbit hole. You’ve got DreamWorks legends, British superstars, and veteran voice actors all playing the same roles at different times.
The Original Four: Why the Directors Stepped In
Initially, the penguins weren't supposed to be a big deal. Tom McGrath, who co-directed the first Madagascar film, originally wanted a "Rat Pack" vibe for the group. He was actually looking for big-name actors to fill the roles. But, as often happens in animation, the "scratch" tracks (temporary vocals recorded by the crew) were just too good to replace.
Tom McGrath himself took on the role of Skipper. He’s the leader. The guy with the grit. McGrath based the performance on the tough-guy personas of 1950s cinema, specifically leaning into a Charlton Heston or John Wayne vibe. It’s a parody of leadership that works because it’s played completely straight. When Skipper barks an order, you believe he believes it.
Then you have Chris Miller as Kowalski. Miller, who directed Puss in Boots, gave the group’s resident genius a voice that sounds like a constant calculation. He's the tall one. The one with the clipboards. Interestingly, Kowalski is often the funniest because his logic is so detached from reality.
Christopher Knights voiced Private. Knights was an editor at DreamWorks, and his soft-spoken, slightly nervous delivery made Private the emotional heart of the team. He’s the "cute and cuddly" one, which is a role he plays with a mix of genuine innocence and occasional, surprising competence.
And then there’s Rico. Rico is a special case. Initially voiced by John DiMaggio (the legendary voice of Bender from Futurama), Rico doesn't really talk. He grunts. He barfs up chainsaws. He’s a tactical psychopath. DiMaggio’s ability to turn guttural noises into a coherent personality is why Rico works at all.

The Movie Stars: Benedict Cumberbatch and John Malkovich
By the time the standalone Penguins of Madagascar movie rolled around in 2014, DreamWorks decided they needed some serious "A-list" weight to round out the cast. They didn't replace the core four, which was a smart move, but they surrounded them with heavy hitters.
Enter Benedict Cumberbatch.
He voiced Classified, the leader of the North Wind, a high-tech undercover task force. It’s hilarious because Classified is everything Skipper wants to be—sophisticated, well-funded, and sleek. Cumberbatch plays it with a refined British arrogance that clashes perfectly with Skipper’s "grit and spit" philosophy. Fun fact: Cumberbatch famously struggled to pronounce the word "penguins" during the press tour, calling them "peng-wings," which became a massive internet meme.
The villain of the film, Dave the Octopus (disguised as Dr. Octavius Brine), was voiced by John Malkovich. Malkovich is known for being intense. Here, he’s intensely weird. Dave is a disgruntled cephalopod who is bitter because the penguins stole all the attention at various zoos. Malkovich brings a theatrical, almost Shakespearean level of petty resentment to the role. It’s one of the best villain performances in DreamWorks history because it’s so deeply personal and strange.
Ken Jeong also joined the 2014 film as Short Fuse, the explosive expert of the North Wind. It’s a smaller role, but Jeong’s high-energy delivery provides a sharp contrast to the more stoic penguins.
The TV Series Shift: Enter Tom Moore and Jeff Bennett
Here is where things get tricky for the fans. When The Penguins of Madagascar transitioned to a TV series on Nickelodeon, the movie stars generally didn't follow. This is standard for the industry—movie salaries don't fit TV budgets.

Tom Moore (sometimes credited as James Patrick Stuart) took over the role of Private. He did an incredible job mimicking Christopher Knights’ original cadence while adding a bit more range for episodic storytelling.
Jeff Bennett stepped in as Kowalski. Bennett is a titan in the voice-over world (you might know him as Johnny Bravo). He brought a slightly more frantic, "mad scientist" energy to Kowalski that suited the fast-paced nature of a 22-minute TV episode.
Danny Jacobs took over as King Julien. While Sacha Baron Cohen voiced the lemur king in the movies, Jacobs became the definitive voice for the TV show and the All Hail King Julien spin-off. Honestly? Many fans actually prefer Jacobs. He captured the flamboyant, narcissistic energy perfectly and earned multiple Emmy awards for it. It's a masterclass in how to take over a character and make it your own.
Why the Casting Works So Well
The cast of the Penguins of Madagascar works because the chemistry is based on archetypes that never get old.
- The Commander (Skipper): The anchor.
- The Brains (Kowalski): The logic that usually fails.
- The Wildcard (Rico): Pure chaos.
- The Heart (Private): The moral compass.
When you add people like Nicole Sullivan (as Marlene the otter) or Kevin Michael Richardson (as Maurice) into the mix for the TV show, the world expands. Richardson, in particular, has one of the deepest, most recognizable voices in Hollywood. His Maurice is the perfect "straight man" to King Julien’s insanity.
There’s also the matter of Conrad Vernon. He’s the director of Shrek 2 and Sausage Party, but he also voiced Mason, the sophisticated chimpanzee who translates for Phil. It’s a small detail, but the fact that so many of these voices come from within the DreamWorks creative team gives the whole project a "passion project" feel. They weren't just reading lines; they were building the characters from the ground up.

Real-World Impact and Misconceptions
People often think the penguins were inspired by real military units. In reality, Tom McGrath has stated they were more inspired by old war movies like The Dirty Dozen or The Great Escape. The casting reflects this. They don't sound like modern soldiers; they sound like 1940s cinema archetypes.
Another misconception is that the cast changed because of drama. It didn't. Animation casting is almost always a matter of scheduling and budget. When a property moves from a $130 million movie to a cable TV show, the union contracts change, and different actors are brought in. The success of the penguins is a testament to the voice directors who ensured that the "sound" of the characters stayed consistent even when the actors behind the mic changed.
Actionable Takeaways for Fans and Creators
If you’re looking to dive deeper into the world of these characters or if you’re a creator looking at how they built such a solid ensemble, keep these points in mind:
- Study the Voice Archetypes: If you're a writer, notice how each penguin represents a specific function within a team. This is why the dialogue is so crisp—you always know how each character will react to a problem.
- Check Out the Spin-offs: Don't skip the TV series just because the movie stars aren't there. Danny Jacobs as King Julien and Jeff Bennett as Kowalski provide some of the best comedic timing in modern animation.
- Watch the 2014 Film for the Guest Stars: Even if you've seen the main trilogy, the standalone movie is worth a re-watch just for the Malkovich/Cumberbatch dynamic. It’s a masterclass in "odd couple" voice acting.
- Listen to the Sound Design: Pay attention to Rico. He’s a reminder that a character doesn't need "lines" to have a massive personality. Sound effects and grunts are just as much a part of the "cast" as the spoken word.
The cast of the Penguins of Madagascar remains a gold standard for how to handle an ensemble. They took what could have been a one-note joke and turned it into a decade-long franchise through sheer vocal charisma and brilliant comedic timing. Whether it’s Tom McGrath’s authoritative bark or Benedict Cumberbatch’s "peng-wings," these performances are why we’re still talking about them years later.
To get the most out of your next re-watch, try to spot the subtle differences between the movie voices and the TV cast. You'll start to hear the unique flourishes each actor brought to the table to keep these birds flying—metaphorically, of course. They're still penguins, after all.
