Ability over Appearance: During Ashley Eckstein's audition for Ahsoka, she was asked to do an Icelandic accent, but her initial performance wasn't what Dave Filoni wanted. When Ashley spoke up in-between takes, Dave liked her own personality and cast her for that reason, encouraging her to place said personality into Ahsoka.
In the Latin American dub, Chancellor Palpatine's two identities were initially played by different actors, with Carlos Segundo (the voice of Darth Maul) as Darth Sidious, and Javier Rivero (the voice of Jar Jar Binks) as the Chancellor persona.
Ahsoka's voice and characteristics are based on Ashley Eckstein after Dave Filoni saw Eckstein's personality in-between audition takes.
The Son having a voice with the tones of Darth Vader, Palpatine, and Starkiller was Sam Witwer's idea (he also voiced the latter two characters in The Force Unleashed).
Alan Smithee: Phil LaMarr revealed in 2020 that he filled in for Ahmed Best as Jar Jar Binks during most of the first season, being credited as "B.J. Hughes". Unlike other examples of this trope, it should be noted that this is the only role of his on the series in which LaMarr was credited by a pseudonym, whereas he is credited by his real name for all his other roles. Given that Best was going through a Creator Breakdown at the time due to harassment he received from being associated with Jar Jar, LaMarr presumably went by the pseudonym to avoid going through the same ordeal.
Ascended Fanon: The nickname for Maul's Mandalorian super commandos, "the Mauldalorians", was acknowledged when one of the Twitter emoji hashtags created to promote the series' revival was #TheMauldalorian.
Blooper: In "Cargo of Doom", when Rex is ordering several battalions of clone troopers into AT-TEs, he calls the first walker an AT-AT... a vehicle that doesn't exist at this point in the Star Wars canon.
Breakthrough Hit: The Clone Wars gave a start to Henry Gilroy, Steven Melching, Katie Lucas, Matt Michnovetz, and Brent Friedman.
Channel Hop: After Disney acquired Lucasfilm, The Clone Wars was pulled from Cartoon Network after its fifth season concluded, and the sixth season was presented on Netflix. Six years later, the seventh and final season premiered on Disney+. The pilot movie, meanwhile, was the first Star Wars film not to be distributed by 20th Century Fox, with the release instead being handled by Warner Bros..
Dave Filoni regrets killing off Steela Gerrera at the end of the Onderon arc. The writers liked her character a lot, but decided to kill her as a sacrifice in liberating Onderon. Even then, Filoni still cited the decision as one of his biggest regrets.
Filoni stated after the series' original run that he didn't like how Darker and Edgier it got as the seasons progressed, personally feeling that it was a reason why some of the viewership went down.
Nalini Krishan, Barriss Offee's actress in Attack of the Clones, felt that Barriss suddenly turning to the Dark Side and betraying Ahsoka was both disappointing and out-of-character.
Averted with Ziro's mother. Despite her masculine-sounding bass voice, she's voiced by Angelique Perrin, whose voice was electronically deepened.
Darkhorse Casting: A few of the lead voice actors were relatively unknown compared to the other roles in the cast; Matt Lanter had supporting roles in live-action TV, and the same goes for Ashley Eckstein in regards to comedy TV.
As the supervising director of The Clone Wars, Dave Filoni does the voice of the bounty hunter Embo and the astromech CH-33P.
Matthew Wood, a sound editor at Lucasfilm subsidiary Skywalker Sound, reprises his role as General Grievous, having previously voiced the character in Revenge of the Sith. He also takes up the roles of Wat Tambor, Poggle the Lesser, and the battle droids.
Died During Production: Ian Abercrombie, Palpatine's voice actor for most of the series, passed away in January 2012, while Season 4 was still airing on television. His last recorded role before his death was Season 5's "The Lawless".note While he also recorded lines for Season 6's Clovis arc, that story arc was originally part of Season 5's production line.
#EngineeredHashtag: The announcement of The Clone Wars' revival came with #CloneWarsSaved as a shoutout to fan campaigns dedicated to saving the series.
Executive Meddling: George Lucas, being the creator and executive producer of the series, had a say in a significant amount of creative decisions (usually for minor concerns) that would override decisions made by the writers. Ziro the Hutt's speech pattern, for instance, came from a last minute suggestion by him. Interestingly, it was also Lucas who suggested to design Cad Bane to be Lee Van Cleefin space and his changes generally didn't interfere with how the stories themselves were told, so it works both ways.
Executive Veto: George Lucas had a tendency to exercise this power in The Clone Wars due to being its creator and executive producer. For instance, "Sacrifice" features the planet Moraband, which was previously known as Korriban. The name Moraband came up during discussion and Lucas suggested that it should be the planet's name in the canon. A writer later added that Korriban is an alternative name for the planet.
God Never Said That: After news of the series' revival, people have said that the series could potentially be extended for more episodes and seasons. This is in spite of the fact that Dave Filoni said in an interview at Celebration Chicago 2019, and later in a D23 inteview, that there aren't any plans for more episodes and season seven would be the final season.
I Knew It!: There were many guesses for what story arcs would be in the seventh season of The Clone Wars, and the three that were predicted were the Bad Batch arc, Ahsoka's Journey arc (albeit modified according to Word of God), and the Siege of Mandalore arc.
The pilot movie went out of print after Warner Bros' distribution contract with Lucasfilm expired, so chances are you'll be paying a lot of money just to get your hands on a DVD and Blu-ray copy of it. Digital outlets won't give you any favors, either. It was available on Netflix (in select regions) from March 2014 to April 2019, but returned to Disney+ upon that service's launch.
WB's home video rights to the first five seasons lapsed several years later, meaning that the sixth season (dubbed The Lost Missions) is the only home video release still in circulation. Fortunately, the entire series, along with its aforementioned pilot movie, was included into Disney Plus.
The "Decoded" versions of the episodes in the first season (re-airings that had some lore blurbs by the Lucasfilm Animation team to go along with them) only aired once on TV and on the official Star Wars website before the premier of the second season.
With the release of season seven and an official finished version of the Bad Batch arc, the original animatics have been taken down from the official Star Wars website (along with the "Legacy" page) and their YouTube channel. While understandable for the Bad Batch episodes (since they've been completed), the Crystal Crisis on Utapau animatics have also been taken down, meaning the only places you can find those episodes are The Lost Missions Blu-Ray release (and only on Blu-ray, as the DVD release never got them) or other YouTube channels if you want to watch them (and YouTube is the only option if you want to see what's changed between the original and finished versions of the Bad Batch episodes).
Limited Special Collector's Ultimate Edition: All the individual seasons' DVD and Blu-ray releases contain massive amounts of bonus content, but the first five seasons' Collector's Edition takes it further: it includes every episode in the series, hours of bonus contents, an episode guide, and the 54-page artbook. Also, it costs just slightly more than half of the combined cost of the individual season releases.
Jesús Colin, Chancellor Palpatine's voice actor in the prequels, had already retired by the time of this series, so he was replaced by Javier Rivero as his Chancellor persona, and Carlos Segundo as Darth Sidious. In season 7, Jesse Conde took over as the official voice of Palpatine/Sidious.
When the four original episodes were edited and released as the pilot movie, Christopher Lee returned to voice Count Dooku. Corey Burton, who plays Dooku for the rest of the series, had already recorded his lines, so Lee rerecorded them and matched his performance to the already-rendered images.
Reality Subtext: Obi-Wan makes a comment in "Old Friends Not Forgotten" about Maul being seemingly killed and coming back again. The same could be said about The Clone Wars itself as Season 7 contains the third series finale.
In Revenge of the Sith, it was originally intended that Yoda would ride a can-cell (the large dragonfly-esque insect first seen on Kashyyyk in that film) to escape Order 66. This was later included into the pilot movie, where Anakin and Ahsoka ride a can-cell to escape Asajj Ventress on Teth.
The seventh season features Ray Park and Sam Witwer provide the motion capture and voice of Maul respectively. They previously did something similar for Maul's appearance in Solo (with Park as the physical actor).
Returning from the films are Anthony Daniels as C-3PO, Ahmed Best as Jar Jar Binks (although Binks was voiced by Phil Lamarr in three episodes), Liam Neeson as Qui-Gon Jinn, Pernilla August as Shmi Skywalker, Peter Mayhew as Chewbacca, Daniel Logan as Boba Fett & the younger clone cadets, and Matthew Wood as General Grievous & the battle droids.
Self-Adaptation: Henry Gilroy, the writer of the Slaves of the Republic comics, wrote its Story Arc adaptation for the series.
Sending Stuff to Save the Show: A number of petitions and campaigns were organized to save The Clone Wars after its initial cancellation in 2013. While it's unknown what effect it had in regards to the sixth season, Dave Filoni and the production crew said that it wouldn't have been possible without the support they got. Even after the sixth season aired in 2014, the support to give it full closure still continued and it finally paid off in 2018 with its revival for a seventh season.
Sequel Gap: The Clone Wars Season 7 premiered on February 21, 2020, making it about six years since the sixth season aired in 2014. To put that into perspective, between the two seasons, Rebels completed its four-season run, Resistance completed its two-season run, and the entiresequeltrilogy was released, on top of a couple spinofffilms and the first season of The Mandalorian.
James Arnold Taylor voices Obi-Wan, Plo Koon, and Osi Sobeck. This was later made into a Significant Double Casting during the Obi-Wan Undercover arc, where James voices both Obi-Wan and Rako Hardeen (both the disguised Obi-Wan and the real Hardeen). This was a deliberate choice in that since Obi-Wan was undercover as him, Hardeen needed to be voiced by someone familiar enough with playing Obi-Wan's character.
Dee Bradley Baker voices all of the clone troopers, as well as Bossk. Throughout the series, there are several scenes and even entire episodes that largely consist of Baker just talking to himself as the clone troopers.
Corey Burton voices Count Dooku, Cad Bane, Ziro the Hutt, and Rish Loo. This gets Played With as the voice of Ziro; the conversations between Ziro and Count Dooku avert this as while the two of them are both played by Burton in the series, they conversed with each other only in the pilot movie, which features Christopher Lee reprising his role as Count Dooku. It is later played straight in "Hostage Crisis" when Cad Bane and Ziro converse after the latter is rescued by the former. Played straight again in "The Box" and "Crisis on Naboo" when Count Dooku teams up with Cad Bane (among other bounty hunters) to capture the Chancellor.
Un-Canceled: In an announcement at San Diego ComicCon 2018, Lucasfilm revealed the revival of The Clone Wars for one final season. The seventh season is created from scripts and story arcs that were originally written before the cancellation and debut on Disney+.
Unfinished Episode: Prior to the series being revived in 2018, the unfinished story reels for the Crystal Crisis on Utapau and Bad Batch arcs were released for free on the Star Wars website.
Ashley Eckstein: From day one, it's been really important for Dave and the rest of the team to record it like an old radio drama and to all be there in person, so it's incredible. We come together for cast records and we're able to really kind of build that camaraderie, which — for us, after working together for so long — we've become like family.
Wag the Director: Or rather wag the creator. When recording for the Obi-Wan Undercover arc, George Lucas initially didn't want James Arnold Taylor to voice Rako Hardeen so that Obi-Wan and Rako sounded different, as the former steals the latter's identity in the story arc. Dave Filoni and the creative team however were confident that Taylor could do a voice that sounded completely different from Obi-Wan and had him voice Rako; they eventually showed his performance to Lucas and he liked it.
Keep Circulating the Tapes: As the old Star Wars website was remodeled in 2012, most of anything from 2011 and before such as the various webcomics, including The Clone Wars ones are lost forever and exist only in screenshots, unless Lucasfilm plans to release them in physical collections as they have with some hard-to-attain media.
