History Trivia / PhineasAndFerb

* FakeBrit: Averted with Ferb's original voice actor, Thomas Brodie-Sangster.However, starting with the ''WesternAnimation/MiloMurphysLaw'' episode "The Phineas and Ferb Effect", [[TheOtherDarrin Ferb's replacement voice actor, David Errigo, Jr.]], plays this straight, as he hails from New York.

* DawsonCasting: The main group of kids have ages 15 or under, according to the creators (with Candace being 15). None of their voice actors have ages falling into that range except Phineas's actor Vincent Martella, who was 14 when the show first started. One of them, Maulik Pancholy, voice of Baljeet, was already in his late thirties (Pancholy was born in 1974). Incredibly, he's not even the oldest - the winner of that particular honor is Kelly Hu, who was 39 when she '''began''' voicing Stacy (Hu was born in 1968)!

** David Errigo Jr. has voiced Ferb ever since the ''WesternAnimation/MiloMurphysLaw'' episode "The Phineas and Ferb Effect", such as in the Creator/DisneyPlus film ''Candace Against the Universe'', and will reportedly continue the role in season five.

** Back then, many of the demos of the songs for the show where uploaded in the early 2010s and where later unlisted but still viewable for a long time. That was until [=YouTube=] made it so that all unlisted videos before 2017 would become private unless the owner makes them public or unlisted again. Since the channel had long been abandoned, all the demos are lost to time. While they did upload them also to Soundcloud, those too where removed later on. They have since been reuploaded onto [=YouTube=] as of March 2024.

** For a ''Broken Karaoke'' short ("All the Ways to Be Anxious" parodying "All the Ways to Be Wicked" from ''Film/Descendants2''), Candace was voiced by vocal impressionist Creator/ShelbyYoung.

*** In the Latin American dub:
** Marco Portillo was the voice of Ferb. He was replaced by Diego Angeles in some episodes midway through the second season, before becoming his permanent replacement since the third season.
** Creator/MarioFilio replaced Germán Fabregat as Dr. Heinz Doofenshmirtz in the Season 1 episodes "A Hard Day's Knight", "I, Brobot" and "One Good Scare Ought to Do It!".

** In the Russian dub, both Phineas and Ferb had their voice actors replaced twice. Once for the second season, and once again for the third season and onwards. The differences between season 1 Phineas, then seasons 2 and 3 is very obvious. (Justified in a way: season one was dubbed in Moscow by SDI Sun Studio Russia, and the rest is done by Nevafilm, albeit in Moscow, too)

* DescendedCreator: Creators Dan Povenmire and Jeff "Swampy" Marsh both voice the major characters of the show's recurring B plot; Heinz Doofenshirtz and Major Monogram, respectively.
** Writer Aliki Theofilopoulous voiced the semi-recurring character of Mandy, the older sister of Thaddeus and Thor.

* IronyAsSheIsCast: While Baljeet has had numerous female {{Love Interest}}s over the course of the show, his voice actor, Maulik Pancholy, came out as gay some time before the end of the show's run.

** Also, the singing voices of female characters during a few songs are sometimes done by men.

* IKnewIt: "For Your Ice Only" confirms what many fans had been suspecting for a long time: [[spoiler: Stacy and Ginger are sisters.]]

* ExecutiveVeto: In the episode "Act Your Age," the subplot is about Doofenshmirtz giving himself a HollywoodMidLifeCrisis. One of the stereotypical things that he was going to do was "get a tattoo that he'll quickly regret." The creators got a note back basically saying "no Disney character will ever be shown in the act of getting a tattoo." Some time later, [[WesternAnimation/Moana2016 Maui]] was introduced.

** Note: Fans tend to overlook that [[http://spongebob.wikia.com/wiki/Dan_Povenmire Dan Povenmire wrote some of older SpongeBob episodes]] and wrote the iconic "Campfire Song." So the aforementioned jab to ''[=SpongeBob=]'' was also good-natured ribbing of his own work.
** Also around this time, Creator/CartoonNetwork was airing [[WesternAnimation/JohnnyTest their own show featuring gadget inventing siblings who also have a braty sibling.]]
