Sony is contending with an unauthorized leak of Spider-Man: Brand New Day's post-credits scene, which was recorded inside a theater and shared across social media platforms starting this week. The studio has deployed copyright claims to remove instances of the footage from platforms like X, though multiple versions remain available online and enforcement efforts appear unlikely to catch all copies.

The leak emerged as the film approaches its official July 31 release, though the movie held its premiere on July 27 with early previews launching the same day, giving certain theaters access to the complete film. Entertainment outlets have cautioned audiences to exercise caution on social media and online forums to avoid inadvertent exposure to major plot details before seeing the film themselves.
