For several James Bond movies, the real British Secret Intelligengen Service building (well, not that secret it seems) was used in the film. In 1999 it can be seen in “The World is not Enough” and much later it gets blown to bits in “Skyfall” (2015). If you would like to see it, you can still visit London and see the real thing. There are also many Bond locations in the area should you be interested (have a look at the London map in Citymaps section).
“Prometheus”, “The Dark Knight Rises”, “Skyfall” and “Harry Potter” have all been here before J.J. Abrahams decided to use this location in the “Force Awakens”.
