Geographical goof
When Jardie and Gerbier arrive in London, we see Jardie in the car with Nelson's Column behind him, and then they drive to Duke St, but on the way we are shown images of Gt. James's St.
Now, as any Londoner knows, Duke St (near Bond St) is northwest of Trafalgar Square, whereas Gt. James's St is about the same distance to the northeast, off Theobald's Rd, not on the way at all.
I am a worthless human being.
What a great film.
