Blade Runner - Easter Eggs & Hidden Details
Easter Eggs
A model of the Millennium Falcon from 'Star Wars' is used as a building in the cityscape.
During the special effects filming, the model makers were in a rush to add more detail to the futuristic Los Angeles skyline. An effects artist who had worked on 'Star Wars' repurposed a model of the Millennium Falcon, turning it on its end and adding some extra parts to make it look like a building. It's a fun nod to Harrison Ford's other iconic sci-fi role as Han Solo. The ship can be seen as Deckard's spinner approaches the police headquarters.
A computer screen in Deckard's spinner car displays a 'PURGE' notification identical to one seen in Ridley Scott's 'Alien'.
When Gaff and Deckard take off in the police spinner, the monitor displays an 'Environmental CTR Purge' message. This exact same screen graphic appears on the shuttle Narcissus's startup sequence in Ridley Scott's 1979 film 'Alien'. This has led fans to speculate that the two films might be set in the same universe, with Weyland-Yutani and the Tyrell Corporation existing in a shared timeline.
