You’ve spent hundreds, maybe thousands, on that perfect 1/12 scale Batman or a pristine MAFEX Spider-Man. He looks great on the shelf. But standing there against a white wall or a wooden bookshelf? It feels... off. Honestly, it’s a bit depressing. To really make these figures "pop," you need a sense of scale, and nothing provides that quite like a gritty, towering action figure city skyline. It’s the difference between a toy sitting on a shelf and a piece of art that looks like it stepped out of a comic book.
Building a believable urban backdrop is tough. It’s not just about stacking boxes. Most collectors fail because they ignore perspective. They buy a flat "cityscape" poster, tape it to the back of an Ikea Detolf, and wonder why it looks like a cheap school play. If you want your toy photography or display to actually look cinematic, you have to understand how light, depth, and materials interact in a miniature world.
The Problem With Flat Backdrops
Most people start by googling a high-res image of New York or Tokyo. They print it out. They stick it back there. Done, right? Not really. Flat prints lack "parallax." When you move your head, the background stays static while the figure moves, which immediately breaks the illusion.
If you’re serious about an action figure city skyline, you need layers. Real cities have depth. Think about the way a dark alleyway recedes into the shadows while a skyscraper behind it catches the moonlight. You can’t get that from a 2D piece of paper. You need physical structures. Even if they are thin. Even if they are just foam board.
Professional diorama builders like Justin Richards or the crew over at Extreme-Sets have basically revolutionized this. They moved away from simple posters toward "pop-up" displays that provide actual physical corners and ledges. Why? Because shadows. A real shadow cast by a plastic gargoyle onto a "stone" ledge looks infinitely better than a printed shadow on a matte surface.
Materials That Actually Work (and Some That Don't)
Foamular. That’s the secret. That pink or blue insulation foam you find at Home Depot. It’s cheap. It’s huge. And you can carve it with a dull pencil to look like brick, concrete, or rusted steel.

Don't use cardboard if you can help it. Cardboard has that tell-tale "corrugated" edge that screams "I made this in third grade." If you do use it, you’ve got to hide the edges with spackle or wood filler. It’s a pain.
Instead, look at XPS foam. You can score it, heat it up to shrink the "mortar" lines, and paint it with acrylics. Just don’t use spray paint directly on it. It’ll melt. Like, literally dissolve into a puddle of chemical goo. You have to seal it with Mod Podge or a base coat of house paint first.
Scale is a Liar
Here is something most people get wrong about an action figure city skyline: you don't actually want everything to be "in scale."
If you are displaying a 6-inch Marvel Legend, a true-to-scale skyscraper would be 50 feet tall. Obviously, that's not happening in your living room. This is where "forced perspective" comes in. You want the buildings closest to the figure to be roughly 1/12 scale, but as the city recedes, the buildings should get smaller. Much smaller.
I’ve seen some incredible displays where the "distant" buildings are actually N-scale or HO-scale model railroad structures. Because they are tiny, your brain assumes they are just really far away. It’s a classic filmmaking trick used in everything from Star Wars to Lord of the Rings.

Lighting the Concrete Jungle
Lighting is where the magic happens. Or where it dies.
If you just use your overhead room light, your city will look like a set. You need directional light.
- The "Rim" Light: Put a small LED behind the buildings pointing up. This creates a silhouette effect for your action figure city skyline, making the buildings look massive and intimidating.
- Window Lights: Use "fairy lights" or small LED strips inside the hollow buildings. Mask off the windows with vellum paper or frosted plastic. This gives that "lived-in" glow of a city that never sleeps.
- Color Temperature: Cities aren't just white light. They are orange (sodium vapor) and blue (moonlight/mercury vapor). Mixing these two creates depth.
Where to Buy vs. How to Build
Not everyone has thirty hours to carve bricks into foam. I get it.
If you have the budget, companies like Extreme-Sets offer "Multiverse" packs. These are heavy-duty cardboard pop-ups. They are great because they fold flat. If you live in a small apartment, being able to tuck a whole city under your bed is a godsend.
Then there’s the 3D printing route. Thingiverse and MyMiniFactory are loaded with files for "Gothic Skyscrapers" or "Sci-Fi Modular Buildings." If you have a resin printer, the detail is insane. You can get air conditioning units, fire escapes, and even tiny trash cans.

But if you’re a purist? You build. You grab some balsa wood for the window frames. You find textured spray paint that mimics the look of asphalt. You spend way too much time weathering the edges with a "dry brush" technique to make it look like the building has survived a few Kaiju attacks.
Common Pitfalls to Avoid
Don't make your buildings too clean. Real cities are gross. They have grime, water stains, and graffiti. Use a "black wash"—basically watered-down black paint—and let it run down the sides of your structures. It settles into the cracks and adds instant realism.
Also, watch out for the "Grid" look. If all your buildings are the exact same height and width, it looks like a military barracks, not a city. Vary the heights. Put a water tower on one. Put a billboard on another. Variety is what makes a skyline feel organic.
And please, for the love of all things plastic, hide your seams. If I can see the tape holding the corner of your building together, the "wow" factor drops to zero.
Actionable Steps for Your First Skyline
Start small. Don't try to build all of Gotham in a weekend.
- Define Your "Hero" Section: Pick one corner or one rooftop where your figures will actually stand. Make this part high-detail.
- The Middle Ground: Create two or three building "flats" (just the fronts) out of foam board. Paint them a neutral grey.
- The Background: Use a printed fabric or a high-quality matte print of a distant skyline. Place this at least 6-12 inches behind your physical structures.
- The "Glow": Add a single blue or purple LED strip at the very base of your background to separate the physical buildings from the printed ones.
- Texture over Color: Don't worry about getting the "right" shade of brick. Worry about the texture. A rough, ugly-painted wall looks more "real" under camera lights than a perfectly smooth, perfectly colored one.
The real trick is to stop thinking of it as a background and start thinking of it as a character. A good city skyline tells a story. It tells us if the world is dystopian, hopeful, or just plain dirty. Once you master the layers and the lighting, your collection won't just be sitting on a shelf anymore. It'll be inhabiting a world.
