The Brand New Day Spider-Man movie is not directly based on the Brand New Day comic storyline, even though it shares the title. Instead, early reporting and trailer breakdowns indicate it is primarily adapting the comic arc “The Other” , a darker Spider-Man story where Peter’s powers evolve and he undergoes a near‑death metamorphosis. At the same time, the movie borrows its name and some status‑quo ideas (Peter forgotten, “fresh start”) from the Brand New Day era of the Amazing Spider-Man comics that followed the controversial One More Day reset.

So, in short:

  • The film’s title and “fresh start” vibe come from the Brand New Day comics era of Amazing Spider-Man (2008 relaunch after One More Day).
  • The core plot and powers/body‑horror elements are reported to be based largely on the comic storyline “The Other” , not on the original Brand New Day run.

If your question is about the comics themselves (not the movie), Brand New Day is an original Spider-Man publishing era, not an adaptation of some earlier comic; it directly follows One More Day in the Amazing Spider-Man series.
