Those murals are based on the 1930s
Winold Reiss industrial murals from the atrium of the Cincinnati Museum Center at Union Terminal, which was the inspiration for the original Hall of Justice in
Super Friends (back when it was still a train station rather than a museum that moonlights as a train station) and which the movie used as a filming location. I assume they digitally altered the Reiss murals rather than tamper with museum pieces.
It's wild to see that a scene from this movie was filmed in a place I've actually been in numerous times in my life. I visited the Terminal a number of times in my youth, including once when my father hosted a radio broadcast from there, and in 1996 I worked there as a museum guide for the
Star Trek Federation Science Exhibit, often taking my lunch break in the very atrium where they filmed. I haven't been there in quite a while, but I can see it from the overlook park near my apartment.
Although it's not the first time a movie has been filmed in a place I know well. When I was in high school, Johnny Cash and Brenda Vacarro filmed a TV movie there called
The Pride of Jesse Hallam, about adult illiteracy. Some of my classmates were extras in the film, though I was too shy to apply. And once on the University of Cincinnati campus, I saw John Sayles filming a scene from
City of Hope, with Joe Morton driving a car on UC's main road (the wrong way on what was a one-way road at the time). But somehow it feels weirder when it's a superhero movie taking place in such a familiar real-world location.
