In exclusive “footage” obtained by The Daily Bugle (and introduced by J. Jonah Jameson played by, yes, J.K. Simmons), the trickster Mysterio (Jake Gyllenhaal) is seen telling the world that Spider-Man actually caused the augmented reality “Elementals” mayhem in Europe. It’s doctored footage of course, but that’s the scary reality we live in now with easily edited videos and machine learning.
Anyway, just before the footage cuts out, Mysterio lets slip that Spider-Man’s real identity is, in fact, Peter Parker. Cut to Peter’s big face on the TV, and Spider-Man cussing out in shock. “What the F—?!”
Peter Parker revealing his identity as Spider-Man is a big plot point borrowed from the 2006 comic book event Civil War. In Civil War #2, Spider-Man willingly unmasks to the world as he joins Tony Stark’s pro-superhuman registration. The unmasking crashed the internet as people flooded Google with “Peter Parker” searches, and gave J. Jonah Jameson at the Bugle a heart attack.
