# Phineas and Ferb season 5

The fifth season revival of Phineas and Ferb is set to air on Disney Channel and Disney+ in the summer of 2025. Created by Dan Povenmire and Jeff "Swampy" Marsh, the series stars Phineas Flynn and Ferb Fletcher (Vincent Martella and David Errigo Jr.), two step-brothers on another summer vacation, while their older sister Candace (Ashley Tisdale) continues her attempts to bust them as the boys' pet Perry the Platypus (Dee Bradley Baker)—who lives a double life as a secret agent—thwarts the evil scientist Dr. Heinz Doofenshmirtz (Povenmire). Confirmed returning supporting cast includes Caroline Rhea as Linda Flynn-Fletcher, Alyson Stoner as Isabella Garcia-Shapiro, and Marsh as Major Monogram.

## Premise

   "The new season of Phineas and Ferb will follow the inventive stepbrothers as they tackle another 104 days of summer. Candace is more determined than ever to finally bust her little brothers while their pet platypus, Perry, continues to lead a double life as the suave Agent P, whose sole mission is to thwart Dr. Doofenshmirtz from taking over the Tri-State area."

## Background

Phineas and Ferb was renewed for a fourth season in August 2011. The-then series finale was announced in May 2015; the hour-long episode, "Last Day of Summer", aired on June 12, 2015. Povenmire and Marsh remained with the network and together created the series Milo Murphy's Law (2016–2019).

## Production
### Writing

Development on the fifth season of Phineas and Ferb began in May 2023, at which point Povenmire confirmed the then-ongoing Writers Guild of America strike. 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.

### Voice 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.

## Announcement and promotion

On January 13, 2023, during the winter press tour for the Television Critics Association, Disney Branded Television announced that 40 new episodes of Phineas and Ferb were ordered, to be split across two seasons, with Povenmire returning as executive producer. The deal also included a second-season renewal for Povenmire's series Hamster & Gretel. In March 2023, it was revealed that Marsh would also return as executive producer and voice director for the revival. 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 first four seasons during a new summer vacation. The duo also previewed a musical animatic which introduces the first episode.

## Premiere

The fifth season of Phineas and Ferb has been given a premiere window on Disney Channel and Disney+ during summer 2025.
