The Two Major Cast Changes Shaking Up Season 5

While the return of the core cast is a reason to celebrate, the revival introduces two significant changes that are already a hot topic of discussion among fans. These shifts highlight the challenges of bringing back a long-running show after a substantial hiatus.

The Recasting of Ferb Fletcher

The biggest change is the voice of Phineas's silent, green-haired stepbrother, Ferb Fletcher. The original voice actor, British star Thomas Brodie-Sangster (known for *Love Actually* and *The Maze Runner*), will not be returning for the new season.

The new voice of Ferb is David Errigo Jr., who has already taken over the role in recent franchise projects, including the 2020 Disney+ film *Phineas and Ferb the Movie: Candace Against the Universe*. Errigo Jr. is confirmed to be the voice of Ferb for the entire 40-episode revival. This change was reportedly subtle, as Errigo Jr. was able to match the character’s low-key, dry delivery, ensuring the dynamic between Phineas and Ferb remains intact.

The Departure of Mitchel Musso as Jeremy Johnson

Another major character receiving a new voice is Candace’s boyfriend, Jeremy Johnson. Mitchel Musso, who also starred as Oliver Oken on *Hannah Montana* and voiced Jeremy in the original run, has departed the series. Musso had voiced the character until 2020.

As of late 2025, Disney has confirmed that Jeremy Johnson has a "fresh voice" but has not yet officially announced the name of the new voice actor replacing Musso. This secrecy has fueled intense speculation among the fanbase, who are eager to know who will be voicing the charming object of Candace’s affection in the new episodes.

The Full Roster of Returning and New Voice Talent

The strength of *Phineas and Ferb* lies in its massive ensemble of quirky, memorable characters. The revival brings back nearly all the fan favorites, ensuring the show’s unique blend of family comedy and madcap villainy remains consistent. Here is the comprehensive list of the confirmed voice cast for the 2025 revival:

• 7 Shocking Things Jessica Capshaw Revealed About Growing Up With Steven Spielberg As Her Stepfather 892ho

• Phineas Flynn: Vincent Martella (Returning)
• Ferb Fletcher: David Errigo Jr. (New to the series, replacing Thomas Brodie-Sangster)

The consistency in the voice talent, especially among the core family and friends, is a testament to the creators' commitment to preserving the original show's identity. The seamless transition for Ferb and the mystery surrounding Jeremy's new voice actor are the fresh hooks that will drive conversation and curiosity as the 2025 premiere date approaches.

Why the Voice Cast is the Key to the Revival’s Success

The decision to bring back almost the entire original *Phineas and Ferb* voice cast, despite the decade-long gap, is a crucial factor in the revival’s potential success. For an animated series, the voices are the true face of the characters, and the unique vocal performances of Martella, Tisdale, and Povenmire are inextricably linked to the show's humor and heart.

The subtle change in Ferb’s voice, handled by David Errigo Jr., is a necessary adjustment due to Thomas Brodie-Sangster’s scheduling and prior commitments, but the character’s quiet nature makes the transition less jarring than it might have been for a more vocal character. Meanwhile, the unannounced recast for Jeremy Johnson adds a layer of intrigue, keeping fans guessing until the revival's release. Ultimately, the return of the original creative and vocal team ensures that the new season will feel like a genuine continuation of the beloved series, proving that even after ten years, some summer days never end.
