5 Of 10 It's Your Birthday!
Before he becomes the awesome Electro, Max Dillon is just a lonely dude who buys himself a birthday cake. The decorative motif on the cake, green with yellow lightning bolts, is a nod to Electro’s costume in the comics.
6 Of 10 The Death Of Gwen Stacy
The hands on the clock are placed very clear and the time Gwen dies at is 1:21 (probably AM). In the comics Gwen Stacy dies in issues #121, which is the time she dies in the movie.
In the movie Emma Stone is wearing the same boots, purple skirt, and mint green coat combo, that Gwen Stacy wears when she dies in the comics. This made it pretty clear to comic book readers that this would be Emma Stone’s last Spider-Man film.
The heartbreaking scene, when Gwen dies in the comics, there is a “snap” that accompanies her death. There is a similarly gruesome crunching noise when Peter’s webbing snares Gwen in the films.
