Over two years ago, Spider-Man: Far From Home in the entire Marvel Cinematic Universe delivered one of the most amazing post-credits scenes. This scene brought J. Jonah Jameson into the franchise. The role is being reprised by J.K. Simmons. He played the same role in Sam Raimi’s original Spider-Man trilogy. The appearance of characters raised many questions from fans, most of which focused on whether he’s just a different version of the character played by the same actor or the same J. Jonah Jameson from the original movies.
We’ll get so many answers about the multiverse in Spider-Man: No Way Home and which Spider-People came from where, but before the film’s debut, Simmons is clearing things up about his character.

Simmons explained that the version of Jameson in the MCU is a modified version of the character he played in Raimi’s original trilogy:
“You know what, I think it’s a slightly different version,” Simmons said. “Certainly, from the creators of the current iteration of the story, it’s a very different character. To me, it’s a slightly different character. It’s the same blowhard, the same guy with less hair. Honestly, I kinda wish he had the same hair…The most important thing is that he’s still the same blowhard, and he does have the same damn mustache and cigar, at least. As is appropriate for that character, he’s a little comic relief thing that gets sprinkled lightly into the movie.”
Jameson has a live streaming channel instead of a newspaper thorugh which he can rile folks up in a much better way. Rather than making Spider-Man look bad in the paper, he’s using technology to hurt the hero actively, making him more of a villain than the previous iteration.
At the end of Spiderman Far From Home, it was Jameson who disclosed the identity of Spider-Man to the entire world. Declaring that Peter Parker is under the mask is the action that sets all of No Way Home’s story into motion. It’s presumed that Jameson will take on a more active and more significant role in this new movie.
