The film features the talents of Sōichirō Hoshi, Rie Tanaka, Akira Ishida, Nanako Mori, Kenichi Suzumura, and Maaya Sakamoto, among others.

Director Mitsuo Fukuda expressed hardships in animating the mobile suits and battle ships due to the usage of CGI and the large amount of mechas the cast uses.

75, a year after the end of the Second Alliance-PLANT War,[b] remnants of an anti-Coordinator terrorist group, Blue Cosmos, continues to lead several attacks on Earth.

The organization's mobile suit commander, Kira Yamato, leads his team; Shinn Asuka, Lunamaria Hawke, and Agnes Giebenrath from the battleship Millennium, to destroy the remnants.

Thanks to the help of Athrun Zala, Meyrin Hawke, and Mu La Flaga, several crewmembers of the Archangel manage to survive the battle; however, Lacus is taken by the Foundation leaders to their base in space.

In the aftermath, Cagalli attempts to mediate between the PLANTs and the Earth Alliance but fails; both sides cut ties with Compass, and its activities are suspended.

ZAFT members Yzak Joule and Dearka Elsman escape the coup and join the Eternal to stop the rogue faction after evacuating the leader of the PLANT supreme council.

An assault team led by Kira infiltrates Foundation's base on the Artemis asteroid and rescues Lacus, as Mu damages and disables the Requiem by reflecting it's blast back to it.

Orphee sorties with Ingrid in his mobile suit, overwhelming Kira along with Shura, but Athrun saves him and engages the latter with the new version of his Infinite Justice.

Yzak, Dearka, the Eternal, and the Kusanagi suppress the rogue ZAFT fleet as Murrue leads the Millennium in destroying Aura's flagship.

Convinced by Lacus and Kira's beliefs about world peace and true love, Orphee and Ingrid accept their defeat, and the war ends.

Lacus, Yzak Joule, and Dearka Elsman will return as members of the PLANT Supreme Council, and Kira, Shinn, and Lunamaria Hawke will be part of the ZAFT military.

[9] However, in 2008, writer Chiaki Morosawa explained that the plot was done, but she has been ill since the end of 2004-2005's Mobile Suit Gundam SEED Destiny series.

Goto does mention that when he was writing for the SEED television series, he found inspiration in foreign dramas he admired, especially those made by sci-fi authors.

[16] Fukuda apologized to the fans for the long development hell the film took, as it was originally meant to come shortly after Destiny.

He reflected on the unfinished drama left by the protagonists of Kira Yamato, Athrun Zala, and Shinn Asuka and thus wanted to explore such possibilities with Freedom.

[17] As in previous works, the mecha were created by Kunio Okawara, with the mechanical animation director being Satoshi Shigeta and Fujita Shinmu at the 3DCG production desk.

A major animation scene that was remade several times was the transformation sequence of Rising Freedom, as the director wanted it to have its own unique feel when compared with previous incarnations of Kira's mecha.

Shigeta cited a transformation scene from Mobile Suit Zeta Gundam, with Fujita expressing relief in retrospect as they could use several colors.

The launch of the Destiny Gundam Spec II and the shooting down of the battleship were the result of several visual effects created by the staff together.

Fukuda finds it challenging to pinpoint what exactly those origins are, but over the course of a year, he has been mulling over how to create a piece that resonates with what they achieved with SEED and Destiny.

[21] Fukuda recounts that his wife, late writer Chiaki Morosawa, wanted to do two things in the movie: have a character, more specifically Athrun, punch Kira due to a lack of violence outside mobile suit fights, as well as sink the Archangel.

The director spoke with him before recording, explaining that although Shin is inherently a bright person, the story's scenes suppress that aspect, preventing him from expressing it.

[25] Fukuda mentioned that while Destiny portrays Shinn negatively, he is much more lighthearted in the movie, returning to his original kind persona due to his good relationship with Kira.

[30] Chiaki Ishikawa had contacted Fukuda when she was chosen to make the ending song, which gave her confidence since the director informed her about the cast's feelings and how she would be able to create a theme.

[57] In retrospect, Dengeki Online enjoyed the handling of Shinn as while he was shocked when seeing him lose his final duel in Destiny, Freedom gives me a more heroic portrayal that appealed to his nostalgia of the TV series even if he has mixed feelings of the character piloting the Immortal Justice.

This was based on the former's design and erotic atmosphere the two pilots have together to the point of comparing them to the cast from mecha anime Darling in the Franxx which had a similar tone in general.

[62] Manga News referred to the film as a "visual magnum opus" thanks to its 3D animation and refined CGI which makes it large amount of fight scenes hard to find problems.

The same site praised the music employed especially the themes from Toshihiko Sahashi who previously worked in the soundtrack from the two TV series.

[59] TVLain felt that viewers should watch the movie in cinemas rather than streaming due to the impressive quality of the animation that would appeal to any mecha fan.
