Prior to last year, the character of J.J. Jameson hadn't appeared in any film adaptation of Spider-Man since J.K. Simmons' portrayal of the character in Spider-Man 3, with only a quick blink-and-you-miss-it reference to the character in The Amazing Spider-Man 2 . Sony seemed well aware that replacing Simmons, who made the role iconic, would be a Herculean effort.
But, the character finally returned in the post-credits scene of Spider-Man: Far From Home with actor J.K. Simmons returning, and now there seems to be a decent chance that the actor will have future appearances in the MCU.
In the latest episode of PeopleTV's Couch Surfing , actor J.K. Simmons discussed his first audition as the editor-in-chief of the Daily Bugle in Spider-Man and later was asked if fans should expect to see more of him in the MCU.
He clarifies "I don't know if I would use the word 'expect'" and goes on to explain that while he is signed on to do sequels, the studio isn't obligated to use him in future movies. However, he expresses gratitude at still being given the chance to play the character again, saying that "It's great to have the opportunity, as these things evolve, to be one of the holdovers from the previous version."
WHAT THIS MEANS
Like most actors that have been hired by Marvel Studios, J.K. Simmons describes having a multi-film contract with the studio. Meaning that while he would be obligated to appear in future movies and sequels, the studio itself isn't obligated to hire him again. After all, Hugo Weaving also had a multi-film contact with the studio and only appeared as Red Skull once, replaced later in Infinity War and Endgame by Ross Marquand.
However, it's encouraging in of itself that Marvel Studios even made a multi-film contract with J.K. Simmons, as this at least indicates that his last-second cameo in Spider-Man: Far From Home wasn't just something to please older fans. This could very well indicate that he'll appear in next year's Spider-Man 3 since he was the one to out Spider-Man's identity to the world, and it would only make sense to bring Simmons back to play the character once again.
