Ark is a 2003 animated science fiction film directed by Subro Adonis, animated by Digital Rim. It is the flagship project for both the director and the studio.

Attempting to address the failures of Final Fantasy: The Spirits Within, the film merges anime-style visuals with a faster, action-oriented plot more palatable to Western audiences.

The film's plot features many archetypes taken from Final Fantasy-style Japanese console RPGs; a young male resistance fighter, a young girl with special powers who unknowingly is her planet's Messiah, an evil "right-hand man", and a small, cute pet mascot. It is the spiritual successor to Elysium (2003) which takes place in the same universe as the film.^{[unreliable source?]}

Ark takes place on a dying alien world of Alcian in which a global war between two technologically advanced human civilizations has reduced the planet to a wasteland. The only way to escape the world is by activating the Ark, an ancient giant robot capable of supporting a human city as well as traveling through space.

James Woods plays Jallak, the military general of the reigning civilization, the Storrians, who captured the Ark from the Ceveans. But they are unable to get the Ark to work in order to save their people. The Ceveans, having been enslaved and with only the wasteland to roam free are constantly attacked and brutalised by the Storrians. A leader of their resistance movement is a young resistance fighter named Rogan. Rogan is arrested during a resistance uprising, but manages to escape. He bumps into the general's adopted daughter Amarinth, whom the general had secretly rescued from a Cevean hibernation pod cluster where they had hidden their children for safety. They then meet again during a civilian protest rally and she offers to help hide him and tend to his wounds. Rogan goes with her back to her apartment and meets her pet JuJu, but then vanishes when he discovers she's the Storrian general's daughter.

Baramanda, the Empress's manipulative right-hand man, arrives unexpectedly to take Amarinth into custody after discovering the truth of her lineage. Rogan helps her escape from Baramanda and takes her to the resistance base within the slave quarters of the Ark. There she meets with an elderly man who explains Amarinth's birthright with the help of JuJu, who turns out to have originally belonged to him. Unknown to Rogan, and to Amarinth herself, she turns out to be the daughter of the Cevean priestess who originally built the Ark, Amiel, who had disappeared 100 years earlier. Amiel helped construct not just the Ark the Storrians hold, but another known as The Ark of York. The plans for the Arks passed down from the Gods (another alien race). It took all her strength to create them, causing her to fall into a deep sleep and not awaken again. Before entering her eternal hibernation, she placed her very young daughter into the hidden hibernation pod. Then her body was secretly hidden by her people until discovered by the Storrians.

They find Amiel's molecular structure enables her body to generate a pulsing electronic field throughout her bloodstream. Not only does this make her body perfectly preserved despite how long she had been inactive, it is the reason the Arks will not work: she and Amarinth are descendants of the gods themselves and only they have the ability to pilot the Arks. A cell of her dead blood can supply power to an entire building, but it becomes apparent that no matter how much energy Amiel's body retains, since she is dead it's not enough to move the ark.

Both civilizations scramble to use Amiel's daughter, Amarinth, to activate their Ark and leave the other civilization behind to die. However, Amarinth, who has ties to both civilizations, wishes to try to find a way to use her power to save everyone. She is opposed by the lifeforce-stealing wraith Baramanda, who wishes to steal the power of the Ark for his own selfish purposes.
