One special piece in my collection is a “Tyrell pyramid” part. In fact, is a discarded piece for Total Recall shooting, thus his red color. But moulds used are the same used in BR pyramid parts. A closer look reveals a lot of tiny details (Scott’s style) and other interesting thing: this part, or an equal one, was used also in the roof of another building in the night landscape while spinners fly in front of the geisha screen ad.
Both pieces pertains to Total Recall possible use. The tiny one cannot be identified as a BR-like one, but anyway was part of the bundle. The letter explaining all the details will be included later.
Some years after I was lucky finding the same piece used in other scene. As you can see in the follow image, the top roof of the building is just this piece, with lights just in the holes of the piece:
A close examen of this screenshot will result identifying some other parts used in the pyramid itself for sure. The reuse of props in the movie was a usual practice.
