Millar saw previsualized footage of the film and said that it exceeded his expectations for the adaptation. He described its first half as being close to the source comic, and added the ending was similar though it was relocated elsewhere from the comic's original setting. The superhero costumes in the series were also removed, with the exception of the leather attire worn by Wesley and Fox. Incidentally, this had been Millar's intent when writing the miniseries, but he and artist J. G. Jones had forgotten to. Millar said, "I wanted them to have those powers and then just wear those costumes for the initiation, but just for one panel. And then I forgot." Millar also stated that he would have liked to keep the supervillain mythos that dictates the original comic in the film. Millar was favorable to most of the changes in the storyline, which includes the story arc of the Fates issuing death orders in line with the series' original theme of predestination.
