Hidden Details

Because of my post about the limited pop cultural footprint of Dungeons & Dragons as a game, several readers pointed me toward the image below, which I've enlarged as much as I could. It's a still from the 1986 Jim Henson-directed, George Lucas-produced, and Terry Jones-penned fantasy movie, Labyrinth. 

In case it's not clear from the image above, there's a copy – seemingly still in shrinkwrap – of the 1981 David Cook/Steve Marsh Expert Set on a bookshelf in the film. I've admittedly not seen the movie recently, but I suspect this is a blink-and-you'll-miss-it moment rather than something that's given any prominence. Certainly, no one in the movie plays D&D or even references it in any way, so I'm not at all convinced that it's particularly relevant to the point of my earlier post. I imagine it's more likely a case that someone on Labyrinth's production team thought the box "looked cool" and then placed it on the set. I doubt anyone before the advent of high-resolution home video even noticed it; I certainly didn't.
I wouldn't be surprised to discover that there are other movies and TV shows from the 1980s that feature, as background details, Dungeons & Dragons and RPG-related paraphernalia. However, I don't believe their number would be very large, or else they'd be better known. I know that, when I was a kid, I made a big deal out of even the flimsiest connections to my beloved hobby. If there are more instances like this out there, they must be very well hidden indeed.
