10 Shocking (But Believable) Spider-Man: Homecoming Theories
10. J Jonah Jameson Is A Woman (At Least In Spirit)
The Theory
Despite him not appearing in any of the marketing, J Jonah Jameson's presence will be felt in the film: he's either being gender-swapped entirely, or he's being replaced by an alternate character with the same spirit.
The answer lies in the mystery role of Tyne Daly, who was added late, but is without a character name so far. It absolutely wouldn't be outside the realms of possibility that she is the cynical, investigative sort of figure replacing Jameson.
Just look at the image of her on set...
Why It's Believable
This might be a whole new Spidey world, but it wouldn't be a Spider-Man movie without recognisable dynamics (which is precisely why there's so much debate over who each character is), and having a sort of secondary anti-hero antagonist would be the right approach.
She might not be actual JJJ, but it would be very believable that she'd be in that position, absolutely.
