You know the sound. That dry, rattling "chirp" of a platypus or the manic, high-energy planning of a triangle-headed boy who really should be in school but is somehow building a roller coaster instead. If you've spent any time on Disney+ lately, you probably realized something: summer is back. But as we dive into the 2025-2026 revival, a lot of fans are scratching their heads. Is that the same guy? Why does Ferb sound... different?
Honestly, the Phineas and Ferb cast voices are basically the DNA of our childhoods. Changing them is like changing the recipe for your grandma's cookies. Some stuff stayed the same, some stuff got a massive upgrade, and one specific voice change has a history that's kinda wild.
The Ferb Situation (And No, It’s Not Who You Think)
Let’s address the elephant in the room. Or rather, the British kid who rarely speaks. For the longest time, Ferb Fletcher was voiced by Thomas Brodie-Sangster. You’ve seen him in Love Actually and The Queen's Gambit. He was the original "man of few words." But if you’re watching the new episodes or the 2020 movie Candace Against the Universe, that isn't him.
David Errigo Jr. is the man behind the mask now.
Why the swap? Basically, Thomas got busy being a massive live-action star. David Errigo Jr. actually started voicing Ferb back in a Milo Murphy’s Law crossover and did such a good job that most people didn't even notice the hand-off. He captures that specific, deadpan British wit perfectly. It’s rare to find a replacement that doesn't feel like a "knock-off," but David nailed it.
Vincent Martella: The Voice That Never Aged
Then there’s Phineas. Vincent Martella has been doing this since he was 13 years old. He’s 33 now.
Think about that for a second.
How does a 33-year-old man still sound like an optimistic 9-year-old? Vincent actually talked about this in a recent press conference for the revival. He literally took opera lessons. Not because Phineas is hitting high Cs, but to increase his vocal stamina and range so he could yell "Ferb, I know what we're going to do today!" without blowing out his voice.
He’s even doing more "extra" voices in the 2025 season—playing random baristas and construction workers. Basically, the creators trust him to do anything at this point.
The "Bustable" Ashley Tisdale
Ashley Tisdale as Candace Flynn is irreplaceable. Period.
There was some worry during the hiatus that she might move on, especially with her own brand and family life blowing up, but she came back with more energy than ever. She’s gone on record saying Candace is the most "limitless" character she’s ever played.
In the recording booth, she’s known for just throwing out random ad-libs and "mom-screams" to see if she can make the creators laugh. If Dan and Swampy (the creators) start cracking up behind the glass, she knows she’s done her job.
The Rest of the Danville Crew
- Dr. Heinz Doofenshmirtz: Voiced by co-creator Dan Povenmire. He basically is the character. His TikTok presence has made Doof more famous now than he was ten years ago.
- Major Monogram: Co-creator Jeff "Swampy" Marsh. He based the voice on old-school news anchors like Walter Cronkite.
- Isabella Garcia-Shapiro: Alyson Stoner is back. She’s been the voice of Isabella since the pilot, and her "Whatcha doin'?" is still the most iconic line in the show.
- Baljeet and Buford: Maulik Pancholy and Bobby Gaylor are both back for the 2025-2026 run. The chemistry between these two is a huge reason why the "bully-nerd" dynamic actually works.
Wait, What Happened to Jeremy?
This is the part that bummed out some long-term fans. Mitchel Musso, who voiced Jeremy Johnson (Candace’s crush), isn't in the revival.
The show hasn't made a big deal about it, but he was replaced. If you listen closely to the new episodes dropping on Disney+, Jeremy has a fresh voice. This follows some real-world legal troubles Musso had in Texas around 2023. While Disney hasn't put out a formal "we fired him" memo, the recasting speaks for itself. It's a bummer for the nostalgia factor, but the new voice keeps the vibe of the "chill boyfriend" alive.
The Secret Weapon: Dee Bradley Baker
You can't talk about Phineas and Ferb cast voices without mentioning the man who doesn't use words. Dee Bradley Baker is the voice of Perry the Platypus.
He doesn't have a script. He just has a "chirp."

Dee is a legend in the industry—he’s every clone in Star Wars: The Bad Batch and Appa in Avatar. For Perry, he makes that clicking sound by vibrating his tongue against the roof of his mouth. It’s a physical feat that most humans can't replicate without getting a cramp.
Why This Cast Still Works in 2026
The reason this show didn't die is because the cast actually likes each other. You see them at New York Comic Con, and they’re genuinely geeking out about the new 40-episode order.
They aren't just "doing voices." They’re protecting a legacy. When Vincent Martella talks about meeting a non-verbal fan who only responded when he spoke as Phineas, you realize this isn't just a paycheck for these guys.
The revival is a continuation, not a reboot. That means the characters haven't aged, but the performances have gotten more nuanced. The music is still there, the "Doofenshmirtz Evil Incorporated" jingle is still there, and most importantly, the heart is still there.
What to Do Next
If you’re looking to catch up on the new era of Danville, here’s your move:
- Check Disney+ for the "Agent P Under C" shorts that just dropped in January 2026.
- Listen for the cameos. The new season has guest stars like Michael Bublé and Meghan Trainor—it’s a game of "spot the voice" every Saturday.
- Watch "Candace Against the Universe" first. It’s the bridge between the old show and the 2025 revival, and it’s where you can really hear David Errigo Jr. settle into the role of Ferb.
