When you sit down to watch a movie like Spider-Man: Across the Spider-Verse, it's easy to get lost in the watercolor explosions and the glitchy, punk-rock aesthetics of Earth-138. But honestly? The visuals would feel like a hollow tech demo without the voice work. We’re talking about a massive ensemble where every single person—from the A-listers to the blink-and-you-miss-it cameos—had to bring a specific, grounded energy to characters that are, quite literally, cartoons.
The Spider Man Across the Spider Verse actors didn't just show up to a booth and read lines. They had to navigate a script that was constantly evolving. If you’ve followed the production stories from Phil Lord and Chris Miller, you know these performers were often recording new dialogue months, or even weeks, before the premiere. It’s chaotic. It’s messy. And somehow, it resulted in some of the best acting in the superhero genre, period.
Shameik Moore and the Evolution of Miles Morales
Shameik Moore just gets Miles. There’s no other way to put it. In the first film, he captured that crackling, awkward energy of a kid who doesn't fit into his own skin. By the time we get to Across the Spider-Verse, Moore has shifted the pitch and cadence of his voice just enough to signal that Miles has grown up. He’s more confident, sure, but there’s this new layer of loneliness that Moore nails.
Think about the rooftop scene with his mom, Rio Morales (played by the incredible Luna Lauren Vélez). The way Moore lets his voice trail off when he’s trying to decide whether to tell her his secret—that’s not just voice acting. That’s a performance. He captures the specific weight of "gifted kid burnout" mixed with the literal weight of saving the multiverse.
Hailee Steinfeld’s Gwen Stacy is the Secret Protagonist
A lot of people walked out of the theater realizing this was just as much Gwen’s movie as it was Miles’. Hailee Steinfeld brings a certain grit to Gwen that we don't usually see in "love interest" archetypes. Probably because she isn't just a love interest. Steinfeld plays Gwen as someone who is deeply traumatized but trying to hide it under a layer of cool, drummer-girl detachment.
The opening sequence of the film, where Gwen deals with her father, Captain George Stacy (Shea Whigham), is heartbreaking. Steinfeld’s voice breaks in ways that feel uncomfortably real. It’s a stark contrast to the chemistry she shares with Moore. Their "hanging upside down" scene is basically a masterclass in vocal chemistry. You can practically hear them smiling through the lines, which makes the inevitable conflict later in the film hurt so much more.
The New Heavy Hitters: Oscar Isaac and Jason Schwartzman
Then we have Miguel O'Hara. Oscar Isaac plays the Spider-Man 2099 role with a terrifying level of intensity. He isn't a villain in the traditional sense, and Isaac plays him with the self-righteous fury of a man who has lost everything and decided that his pain justifies his pragmatism. There’s no humor in Isaac’s performance. He’s the "straight man" of the multiverse, and his deep, echoing growl provides the perfect foil to Miles’ kinetic energy.

On the flip side, you have Jason Schwartzman as The Spot.
At the start, Schwartzman plays Jonathan Ohnn as a total joke. He’s "the villain of the week." His voice is high, wavering, and deeply insecure. But watch how Schwartzman shifts that performance as the movie progresses. By the final act, that insecurity turns into a cold, echoing void. It’s one of the most underrated transitions in the film. He goes from being a guy who can't even rob an ATM to a genuine multiversal threat, and the shift is entirely in the vocal delivery.
Daniel Kaluuya Stole the Whole Movie
We have to talk about Hobart "Hobie" Brown.
When it was announced that Daniel Kaluuya would be playing Spider-Punk, people were curious. Kaluuya is an Oscar winner known for intense, dramatic roles in Get Out and Judas and the Black Messiah. But as Hobie? He’s having the time of his life. He uses his natural Camden accent and imbues the character with this effortless, anti-establishment charisma.
Hobie could have been an annoying "cool guy" trope. Instead, Kaluuya makes him the moral compass of the film. He’s the only one who truly sees Miles as an individual rather than a "calculation" or an "anomaly." Every line Kaluuya delivers feels like he’s leaning back in a chair with his boots on the table, completely unimpressed by the Spider-Society’s bureaucracy. It’s iconic.
The Supporting Cast and Those Wild Cameos
The depth of the Spider Man Across the Spider Verse actors list is honestly staggering.

- Jake Johnson as Peter B. Parker: He’s back, now as a "Spider-Dad." Johnson brings that same tired, lovable energy, but now with the added chaos of carrying a baby (Mayday) in a harness.
- Issa Rae as Jessica Drew: She plays the pregnant Spider-Woman with a no-nonsense authority. She’s the mentor Gwen needed, even if she’s on the "wrong" side of the central conflict.
- Karan Soni as Pavitr Prabhakar: He brings an infectious, high-speed energy to Spider-Man India. His rant about "Chai tea" (tea tea!) is a highlight of the script's humor.
- Brian Tyree Henry as Jefferson Davis: As Miles’ dad, Henry provides the emotional anchor of the film. His speech to Miles through the bedroom door is arguably the most important scene in the movie for Miles' character arc.
And then there are the cameos. We got Donald Glover appearing as a live-action Prowler, which was a massive nod to the fan casting that originally helped inspire the creation of Miles Morales. We had archival footage of Andrew Garfield and Tobey Maguire. We even had Yuri Lowenthal voicing the "Insomniac" Spider-Man from the PlayStation games. The sheer scale of coordination required to get these actors into one project is a logistical nightmare that turned into a fan's dream.
Why the Voice Acting Hits Differently
In most big-budget animated films, studios hire "big names" just to put them on the poster. Sometimes it works; sometimes it feels like a celebrity just talking into a mic.
In Across the Spider-Verse, the casting feels intentional. Each voice is a texture.
The directors used a process called "line-acting," where they encouraged the actors to overlap, mumble, and ad-lib. This is why the dialogue feels so fast-paced and natural. When Miles and his parents argue, it sounds like a real family dinner where everyone is talking over each other. It doesn't sound like people waiting for their cue in a soundproof room.
The Challenges of the Multiverse
One thing people get wrong about this cast is assuming it was an easy gig. Because the animation style changes for every world (Gwen’s world is impressionistic, Mumbattan is bright and kaleidoscopic, the Spider-Society is brutalist), the actors had to adapt their performances to fit the "vibe" of the scene.
Oscar Isaac had to sound like he belonged in a high-tech, oppressive future. Daniel Kaluuya had to sound like he was stepped out of a 1970s London punk zine. The vocal performances act as the glue that holds these wildly different visual styles together. If the acting wasn't grounded, the movie would just feel like a series of disjointed art pieces.

What’s Next for the Cast?
With Spider-Man: Beyond the Spider-Verse on the horizon, the stakes for these actors are even higher. We know that Moore, Steinfeld, and Isaac are all returning. We also know that the "Spider-Band" (Gwen’s new team at the end of the film) will be central. This means more of Karan Soni, Daniel Kaluuya, and Kimiko Glenn (Peni Parker).
The real question is how they will handle the introduction of even more variants. The bar has been set incredibly high. Each actor in this franchise has managed to make their version of Spider-Man feel like "the" Spider-Man of their own story, not just a background extra.
Actionable Insights for Fans and Creators
If you’re looking at this cast and wondering why it works so well, there are a few key takeaways:
- Chemistry Matters: Even in animation, the "spark" between Miles and Gwen is real because the actors recorded together when possible or worked off very specific emotional temp tracks.
- Diversity is a Strength, Not a Gimmick: The cast includes people from all over the world, bringing authentic accents and cultural nuances (like Karan Soni’s Pavitr) that make the multiverse feel truly vast.
- Trust the Performers: A lot of the best moments, like Hobie’s witty one-liners or Peter B. Parker’s exhausted dad jokes, feel like they came from the actors inhabiting the characters, not just reading a teleprompter.
If you want to dive deeper, check out the "Behind the Scenes" features on the digital release. Seeing Shameik Moore and Hailee Steinfeld in the booth gives you a whole new appreciation for the physical effort that goes into these vocal roles. You can see Moore physically moving like Miles as he speaks, which is probably why the animation looks so synced to his soul.
The Spider Man Across the Spider Verse actors didn't just voice a movie; they defined a generation of what superhero stories can actually be. They proved that even when you’re dealing with infinite realities, it’s the human (or spider-human) heart that matters most.
