Continuity mistake: During the scene where Akima gets out of the shower, we see Cale going over some of the stuff she collected that's sitting on her table. On it there is a baseball and a picture frame that's lying flat on the table. Cale picks up the baseball, says something to Akima and puts the baseball back down on the table, where it rolls over the picture frame as if it was flat as the table.
Continuity mistake: During the movie, the tattoo on Cale's arm grows and shrinks. In some shots it is tiny, and in others it takes up nearly all of his upper arm.
Continuity mistake: The good guy is shot in the arm and while he is riding on the top of the little ship he drips blood on the glass canopy, the blood then vanishes.
Continuity mistake: In the beginning we see him floating a water toy and the stem breaks off in the water on some rocks. Yet when it's pulled out of the water the stem is back.
Continuity mistake: When Akima and Stith are firing at the Drej at the end of the movie, the graphics on the readout is completely inaccurate with the scene. 1) When Stith says that she only has two guns left, the screen says that she only has one left. 2) After Akima loses all of her guns, the display on Stith's screen shows that Akima has several guns left. 3) After all guns are destroyed, when Akima notices that Korso is outside with Cale, the screen shows that there is one gun left.
