Concept: Retro-Futuristic London, Houses of the Parliament
So the London we will see in the film, is a retro-London, a vision how the English Capital would look 50 years from the time the film is set, 1950. This also coincide with the year 2000, and despite London not looking like this now, filmmakers of the time had a quite vivid idea how the future would look like.

P.S: I used a wider version than the regular 16:9, for a panoramic look.
Alongside the painting is the progress I have done, and the choices I had to take.
