Matt Lanter voices Anakin Skywalker, the Jedi Knight who takes on Ahsoka Tano as his apprentice in Star Wars: The Clone Wars (2008). In a 2021 StarWars.com feature, Lanter said he had no idea he was auditioning for Anakin, because the part was pitched under the name Deak Starkiller. Dave Filoni asked for his best combination of Luke Skywalker and Han Solo, and that reading won him the role.
Ashley Eckstein as Ahsoka Tano (voice)
Ashley Eckstein voices Ahsoka Tano in Star Wars: The Clone Wars (2008), the headstrong young Padawan assigned to Anakin as his apprentice. StarWars.com notes that Ahsoka was introduced in this animated movie, which makes the film her first appearance. Eckstein told the site that Dave Filoni saw a lot of her own personality in the audition, and that how she behaved between takes counted as much as the reading.
James Arnold Taylor voices Obi-Wan Kenobi in Star Wars: The Clone Wars (2008), along with two smaller droid parts credited as 4A-7 and Medical Droid. He was not new to Kenobi in 2008: SYFY Wire reports that he has voiced the prequel era Obi-Wan ever since the Genndy Tartakovsky animated version, and he carried the role into this film's opening battle on Christophsis.
David Acord as Rotta the Huttlet (voice)
David Acord voices Rotta the Huttlet, the infant son of Jabba the Hutt, in Star Wars: The Clone Wars (2008). The baby's kidnapping drives the main plot, because the Jedi are asked to bring him back to win the Hutts' cooperation. Acord is billed fourth in the TMDB credits for the film.
Dee Bradley Baker as Captain Rex / Commander Cody / Commander Fox / Clone Troopers (voice)
Dee Bradley Baker voices Captain Rex, Commander Cody, Commander Fox and the rank and file Clone Troopers in Star Wars: The Clone Wars (2008). In an October 2008 interview with Animation World Network, Baker said he starts from a core voice such as Rex and then adds one or two personality traits for each clone, recording them separately so that identical soldiers still sound like individuals.
Christopher Lee voices Count Dooku, the Sith Lord on the Separatist side of the war, in Star Wars: The Clone Wars (2008). Lee had played Dooku in Attack of the Clones (2002) and Revenge of the Sith (2005), and StarWars.com confirms that he returned to the role for this animated movie. Screen Daily also names him among the three actors reprising live action roles here.
Nika Futterman as Asajj Ventress / Tee-C-Seventy (voice)
Nika Futterman voices Asajj Ventress in Star Wars: The Clone Wars (2008), and she also has a smaller credit as the droid Tee-C-Seventy. The film began a long partnership with the character, since StarWars.com noted in May 2025 that Futterman has voiced Ventress ever since the 2008 movie. She told the site that she feels she has become the character.
Kevin Michael Richardson as Jabba the Hutt (voice)
Kevin Michael Richardson voices Jabba the Hutt in Star Wars: The Clone Wars (2008), where Jabba's infant son is kidnapped early in the story. The need to get the child back is what sends the Jedi on their mission, so the role frames the main plot even though much of the action happens far from him. Richardson is billed eighth in the TMDB credits.
Catherine Taber voices Padmé Amidala in Star Wars: The Clone Wars (2008) and is billed ninth in the TMDB credits. Screen Daily's August 2008 review names three actors who return from the live action films (Samuel L. Jackson, Anthony Daniels and Christopher Lee). Padmé is therefore one of several principal characters voiced in this film by a performer who did not play the role on screen.
Ian Abercrombie voices both Chancellor Palpatine and Darth Sidious in Star Wars: The Clone Wars (2008), a double credit that covers the public face and the hidden identity of one character. The A.V. Club, reporting his death in January 2012, noted that he took over the part in his later years for this film and for its television and video game adaptations.
Corey Burton as Ziro the Hutt / General Loathsom / Kronos-327 (voice)
Corey Burton voices three characters in Star Wars: The Clone Wars (2008): Ziro the Hutt, General Loathsom and Kronos-327. Screen Daily's August 2008 review mentions his Ziro the Hutt by name. Several actors in this film take more than one part, and Burton's three credits match James Arnold Taylor's and Tom Kane's. Dee Bradley Baker has the most, with four (Captain Rex, Commander Cody, Commander Fox and Clone Troopers).
Tom Kane voices the Narrator, Yoda and Admiral Yularen in Star Wars: The Clone Wars (2008). Reporting his death at 64 in May 2026, TheWrap listed Yoda in The Clone Wars among his biggest roles, and said he voiced Yoda throughout the series' run on Cartoon Network and Disney+.
