According to rumors, Willem Dafoe--who played the role of Norman Osborn/Green Goblin in the original Spider-Man film, has been spotted on the set of "Spider-Man 3."
More and more hints suggest that a crossover in "Spider-Man 3" is really happening. The possibility of Spider-Verse occuring in "Spider-Man 3" is getting more real now, especially after the reported return of another character.
The "Spider-Man" versions of Tom Holland, Tobey Maguire and Andrew Garfield could actually be together in one film, especially if a recent teaser is to be believed.
