I’ve been watching the third season of Bosch on Amazon Prime Video. In one episode, I noticed a detail that intrigued me.

Harry Bosch (Titus Welliver) lives in a house partly supported by stilts, on a hillside in the Hollywood Hills, just as in the books. In one shot I noticed a framed poster on a wall.

It was a poster for a movie or a novel (I couldn’t tell) called The Black Echo.

The Black Echo is one of the novels this season of the show is based on.

So even if you imagined that a book had been written or a movie made about Bosch’s adventures (such a made-for-TV movie is in fact a plot element), and called The Black Echo, there’s no way either one could have been done about an adventure that isn’t even over yet.

The poster is a wink at the viewer from the production team. A very subtle breaking of the proscenium.

I expect that sort of thing happens more in movies and TV than I’m aware of.
