As Spider-Man: Brand New Day approaches its July 31 launch, the film's final trailer has been released, featuring several new scenes alongside a recap of previous events.

The trailer begins by reminding viewers of key plot points from Spider-Man: No Way Home, including Peter Parker's (Tom Holland) friendship with Ned and his relationship with MJ, before their memories of him were erased. Director Destin Daniel Cretton has indicated that the film's title, "Brand New Day," reflects Peter's journey towards finding a sense of renewal.

New footage includes a moment where Bruce Banner, in his Hulk persona, declares, "No Banner! Only Hulk!" Spider-Man also delivers a quip to a group of ninja monks from the criminal organization The Hand, asking, "Could we do this one at a time, please?!" The trailer concludes with Ned observing Spider-Man's presence before realizing the superhero is standing directly in front of him.

Despite being the final promotional trailer, Marvel and Sony have withheld significant details. The identity of Sadie Sink's character remains a central mystery, with director Cretton stating it is being kept secret for a "very real reason" that he believes fans will not object to. Sink herself has been largely obscured in trailers, though she makes a brief appearance in a reused shot wearing a large coat and hood. Online speculation heavily favors Sink portraying Jean Grey from the X-Men.

The film's narrative will address whether Ned and MJ regain their memories and explore Peter Parker's circumstances leading into the upcoming "Avengers: Doomsday" and "Avengers: Secret Wars."
