While some actors wish to join either DC Universe or Marvel Cinematic Universe, J.K. Simmons had the privilege of appearing in both cinematic universes. Simmon first appeared as J. Jonah Jameson in Sam Raimi's Spiderman Trilogy, featuring the first-ever Spiderman, Tobey Maguire. For DC, Simmons appeared as Commissioner James Gordon in 2017's Justice League and was reported to reprise his role as Commissioner Gordon for the upcoming HBO Max series, Batgirl. While Ben Affleck seems to be out of the series, Simmons will be interacting with the new Batgirl.
In a recent interview by Variety, while attending Critics Choice Awards, Simmons made a shocking revelation about his roles from both cinematic universes. The actor revealed that he doesn't have an idea of how these multiverses work and that he just gets there to do his job.
Simmons explained, "It's super cool to be, and for there to be room in the Marvel Universe, as we've seen, and in the DC Universe for these alternative universes or realities or whatever they are, I don't know… I have no idea. They write a script and I learn the lines and the director says, 'Stand over there.'"
As an actor, being involved with both complex cinematic universes by DC and Marvel will be really confusing. Given Simmons' appearance in multiple multiverse-related roles, it would be really hard to track each story that your character is currently involved.
Simmons recently made a cameo for Holland's Spiderman: No Way Home and reprised his iconic role as J. Jonah Jameson, Simmons' cameo is actually one of the highly-anticipated comebacks aside from Tobey Maguire and Andrew Garfield's appearance in the film. Simmons is also reported to have more MCU appearances in the future, specifically for the Spiderverse that the MCU is currently developing. While the MCU's multiverse saga is a complex storyline if you haven't seen all the TV shows and films related to the new storyline after the Infinity Saga, adding DCEU's tangled web of stories would be incredibly difficult to decipher.
For the award-winning J.K. Simmons, we can't blame him if he loses track of the complex stories that his character is involved. It's not very necessary for an actor to fully understand how each universe connects to another, as long as he portrays his roles in the most satisfying way that the audience would love, his performance and the script are all that matters.
