Picture the walk to your screening room. The carpet, the smell of popcorn, the posters lined up along the hall like little doorways you never get to open. I kept thinking: what if you could? What if the wait for a movie was already the first scene of it? This is an AR concept that turns a theater hallway into the opening of the story.
00 – The idea spark
Movie posters are the most wasted surfaces in the building. You pass a dozen on the way to your seat and they just hang there, holding still. I wanted to give the most magical franchise I could think of, Harry Potter, a hallway that behaved like Hogwarts: portraits that move, objects that fly, walls that refuse to sit quietly.
01 – The Golden Snitch in flight
The poster becomes a window
By the first Harry Potter poster I placed a small invitation: scan me. Point your phone at it and a 3D Golden Snitch flutters loose, darting around the frame and just out of reach, the way it does on the pitch. The poster stops being a picture and starts being a window into the world behind it.
02 – The moving Sirius Black poster
A wanted poster that stares back
The second poster is Sirius Black, and if you know the films you already know what it wants to do. Scan it and the WANTED notice comes alive, the photograph shifting and glaring out at you, exactly like the Daily Prophet pages that never hold still. Fiction folded neatly onto a real wall.
03 – Dive into the trailer
A private pre-show in the hallway
The third poster goes furthest. Scan it and it doesn’t just animate, it plays, rolling the latest trailer right there on the wall. A walk to your seat becomes a private little pre-show, and the anticipation starts long before you’ve found row H.
04 – A magical ticket to Hogwarts
The spell starts in your hand
Then I reached past the screen entirely. Your ticket isn’t a flimsy stub, it’s a replica of the Hogwarts Express ticket from Platform 9¾. Flip it over and there’s a QR code waiting: scan and experience the magic. The whole thing begins before you’ve even reached the hall.
05 – Behind the scenes
How it was built
I made it in Unity 3D with ARCore: the graphics, the animation, and the image-tracking all stitched together so a phone could recognize a poster and drop the right bit of magic onto it in real time. The hard part was never the 3D. It was making something this elaborate feel effortless to a person just trying to get to their seat.
06 – The impact
What I love about this one is the quiet argument underneath it: that promotion doesn’t have to be something done to you. A poster can be an invitation instead of an advertisement. AR can take the dead minutes of everyday life, the waiting, the walking, and turn them into play.
It made promotion feel like an invitation, not an advertisement.
07 – Final thought
This started as a Harry Potter daydream in a movie hallway, but the idea outgrew the franchise fast. As the tech gets better, the question stops being “can we” and starts being “where else”. I keep coming back to that hallway, and how good it felt to make waiting feel like wonder.
scan, and let the adventure begin.
