Years ago, I bought a storage unit full of Jennings J400 slots (30 of them) from my neighbor in Illinois, Alan Sax, who many of you know. I had plans to restore them and build a "slot wall" in my game room but never did. So they sat stacked up, collecting dust.
A few years ago, a set designer contacted me in search of slots; he wanted to rent about eight of them to use as props for a then-unnamed movie. We went back and forth and finally I negotiated a deal where the studio would purchase 24 of them from me. I rendered them non-functional because they were only looking for props, not useable machines. Removed most of the insides and explained to their electrician how to make the reels spin if they wanted them to look authentic.
I then shrink-wrapped the machines on pallets and shipped them out to a studio in Canada.
Maybe 4-5 months later, I discovered that they were used as a mock casino in the movie "Bad Times At The El Royale" which starred Jeff Bridges and Chris Hemsworth, among other well-known actors.
The studio changed all the graphics, added special lighting inside and used them throughout the movie, serving as backdrops during filming. One of the last scenes in this movie was in "Reno" and virtually all of these machines were set up in a casino, and the appearance was about as real as it gets. Pretty impressive since none of them actually functioned.
Here's the end scene:
