Which Marvel comic storyline gave Spider-Man: Brand New Day its title?

Spider-Man: Brand New Day takes its title from the 2008 Marvel Comics storyline Brand New Day.

In the comics, Brand New Day followed the controversial One More Day storyline and reset Spider-Man's status quo. The storyline began in The Amazing Spider-Man #546, published in 2008, and presented a new direction for Peter Parker.

The film is not a direct screen adaptation of every event in the comic storyline. Instead, its title signals a thematic connection: Peter enters a changed phase of life after the events of Spider-Man: No Way Home.

The film's Peter is living alone, is unknown to the people who once loved him, and is devoted to being Spider-Man. That idea of a reset or fresh beginning connects the movie's title to the comic-book source while allowing the MCU to tell its own story.
