The revival and fifth season of Phineas and Ferb premiered on Disney Channel on June 5, 2025, with the first ten episodes released on Disney+ the following day. Created by Dan Povenmire and Jeff "Swampy" Marsh, the series centers on stepbrothers Phineas Flynn and Ferb Fletcher, who spend their summer vacation building elaborate inventions, while their older sister, Candace, repeatedly attempts to expose their antics to their mother.

Development began in May, with voice recording commencing by September. The writers' room featured both new and returning writers, and notably saw Vanessa Doofenshmirtz's actress Olivia Olson join her father Martin as a writer. The season has received praise for its return to form, entertainment value, cast performances and characters, although some criticised its lack of reinvention.

Production

Background and development

Phineas and Ferb was renewed for a fourth season in August 2011. Originally set to be the final season, it concluded with an hour-long finale, "Last Day of Summer", on June 12, 2015. Povenmire and Marsh remained with the network and together created the series Milo Murphy's Law, after which Povenmire solely created the series Hamster & Gretel. In April 2019, Disney announced a one-off film, Phineas and Ferb the Movie: Candace Against the Universe, and that it would be released on its then-new streaming service Disney+; the film premiered on August 28, 2020. On January 13, 2023, it was announced that a deal between Povenmire and Disney Branded Television would renew Hamster & Gretel for a second season, and revive Phineas and Ferb for two new seasons with 20 episodes each. In March 2023, it was revealed that Marsh would also return as executive producer and voice director for the revival.

Writing

Development on the fifth season of Phineas and Ferb began in May 2023, at which point Povenmire confirmed the then-ongoing 2023 [Writers Guild of America strike|Writers Guild of America strike] would not affect its production. Povenmire and Marsh admitted their concerns that they would have trouble coming up with new ideas for the revival, but explained those concerns were alleviated due to their confidence in the writers' room, which contained both returning and new writers. They cited seven episodes in particular as standouts which they felt would appeal most to the returning audience. Marsh said that the returning animators had the benefit of the time to conceive many ideas they had wished were done in the original run, while the new animators brought "energy" to the writers' room with their appreciation of the show's run during their childhoods. Vanessa Doofenshmirtz voice actress Olivia Olson joined the writers' room this season, after shadowing under her father Martin Olson—who wrote for the original run—as a writing team with him.
Among the biggest changes to the series was that episodes were script-driven rather than storyboard-driven, reflected in the narratives of episodes like "Deconstructing Doof" and "Lord of the Firesides". Povenmire stipulated that the storyboard artists were still given creative freedom, just that they were given more information and flexibility with the creative process. Povenmire pointed out the challenge of writing "Meap Me in St. Louis", based around the incorporated scenes in a fake movie trailer shown in a previous episode, with most shots being entirely recontextualized beyond expectation.

Animation

This season sees the debut of new art director Nadia Vurbenova, and workflow with animation is managed via the Storyboard Pro digital program used on Cintiq tablets. Having previously worked on Candace Against the Universe and Hamster & Gretel, Filipino animation studio Snipple Animation works on the season. Main poses are done by local animators while Snipple handles the inbetweening.

Recording

Voice recording began by September 2023, and was not affected by the then-ongoing 2023 SAG-AFTRA strike. Candace Flynn actress Ashley Tisdale was concurrently pregnant during voice recording and refused to record new screams, feeling it would "scare the baby"; she suggested the producers use any of her "17 years" worth of archive audio instead.
The opening credits theme has undergone slight changes for the new season; the first line was changed to "There's another 104 days of summer vacation", and Phineas Flynn actor Vincent Martella re-recorded his lines for consistency with how Phineas sounds temporally.

Promotion

In April 2023, a press release commemorating the 40th anniversary of Disney Channel confirmed that the revival will air on the network. The revival was originally scheduled to be released in 2024. At Disney Television Animation's presentation during the Annecy International Animation Film Festival in June 2024, Povenmire and Marsh made an appearance to promote the series and give details on the production. They specified the revival was being treated as "Phineas and Ferb season 5", and that it would take place in the following year after the events of the season 4 finale, "Last Day of Summer", during a new summer vacation.

Reception

On Rotten Tomatoes, 100% of 9 critics gave the season a positive review. Rolling Stones Alan Sepinwall declared his relief at the return of something as "funny, optimistic, joyous, and inventive" as Phineas and Ferb". Colliders Aidan Kelley wrote the season retained the same "vibrant animation, well-written characters, and infectious sense of humor", and remarked it did not need to differentiate itself from past seasons in order to "spread its infectious positivity"; The Seattle Timess Chase Hutchinson wrote it was "plenty silly, with knowing gags galore and plenty of ridiculous musical numbers", without losing its ability to derive enjoyment from a solid forumula. ComicsBeats Tim Rooney wrote that Phineas and Ferb "reclaim its throne as the most fun family friendly entertainment on TV".
Screen Rants Abigail Stevens and Colliders Kelley both felt the first two episodes were only just adequate enough as a premiere, describing them as "just big enough" to serve as a return so that the series could get on with its formula, and "just a little too safe"; Rolling Stones Sepinwall noted the series addressed the "high bar" the earlier episodes set for itself by having Doofenshmirtz admit he was "starting slow" with his -inators and the titular duo insisting they could top themselves this time around; and The Seattle Timess Hutchinson wrote that the season "settles back into comfortable comedic rhythms", while "playfully" acknowledging it has a "lot to live up to". ComicsBeats Rooney felt the first half of the premiere was a show of confidence while the second was a bold display of emotion and drama reflective of the collective confidence of the series's staff. Colliders Kelley and Rolling Stones Sepinwall both noted the 2015 ending of the series's story as the characters embarked to college, and agreed the series needed to be innovative to justify its existence in the time between then.
Stevens felt Doofenshmirtz's return to evil was the worst character regression, ComicsBeats Rooney recognized the writing's self-reflexive-ness in returning the villain to his hero, Perry, while Colliders Kelley hailed him as the standout, praising what they guessed was "stellar improvisational humor" from Povenmire and opining his dynamic with Perry was the best amongst the series's dynamics. Rolling Stones Sepinwall compared the focus on the series's supporting characters to that of the fourth season, and pointed out episodes that expanded upon previously established plot points, such as Stacy's knowledge of Perry being a secret agent and Buford having life-size molds of the main cast; ComicsBeats Rooney praised the cast for "effortlessly" returning to their roles, singling out Martella for sounding the same in his 30s as he did during the original run.
Stevens noted the signs of Phineas, Ferb, and Candace growing up despite the "debatable" idea of the series having character development during its floating timeline. She further opined the subsequent episodes were slightly inferior in quality to the original run, nonetheless praising the inventions, and the "snappy" and "dynamic" musical numbers. Rolling Stones Sepinwall admitted he saw nothing save one exception in the five episode sampler he watched that he felt could stand up to the original run's best, but lauded the series's ability to return after so long and still feel like itself as a "remarkable achievement". The Seattle Timess Hutchinson wrote despite it not breaking much new ground, it still was "breath of fresh air" and its message of creativity was an amiable effort towards young people. Stevens praised the lessons about family, friendship, and creativity amongst the "small bits of growth very subtly laid out" she could see the makings of.
