The Amazing Spider-Man 2: El poder de Electro

The humorously hateful news boss J. Jonah Jameson, one of the most iconic characters in Spider-Man's mythos, was never mentioned in The Amazing Spider-Man (2012). In this sequel he is spoken of frequently but never appears. The producers claimed they could not find an actor to measure up to J.K. Simmons' legendary portrayal of this character in Sam Raimi's Spider-Man films. Stan Lee, the writer who came up with the idea for these characters and makes cameo appearances in all the films, has often said he would volunteer to play Jameson if he (Lee) were 30 or 40 years younger. Ironically, when casting Spider-Man: Lejos de casa (2019), they could still think of no one better than Simmons, so he resumed his role as Jameson.

(at around 41 mins) When Harry Osborn and Peter Parker are walking though the park, the camera crew and boom are reflected in Harry's mirrored sunglasses.

During the end credits, several schematics can be seen of the Rhino suit, the Green Goblin glider, the metallic Vulture wings, the mechanical Doctor Octopus tentacles, and other obscure weapons.

The German theatrical version plays the German song "Ohne zurück zu sehen" by Tim Bendzko over the end credits.
