J.K. Simmons has revealed that he has signed on to return as J. Jonah Jameson in future Spider-Man films from Marvel and Sony.  However the actor says to not get to excited too quickly and to keep expectation dialed down:

“I don’t know if I would use the word ‘expect’,” he said cagily in a new interview with PeopleTV’s Couch Surfing podcast. “When we signed on for the first movie, we signed a contract to do two sequels as well, which is always …that’s always a one-sided – not always, I guess, but in my case – a one-sided contract where you, y’know, you’re committed to do it, but they’re not necessarily committed to, y’know, use your character in the ensuing movies, so it’s great to have the opportunity, as these things evolve, to be one of the holdovers from the previous version.”
