Factual error: A Humber Pullman, reg no UJ7 847 is in the scene where the Duke of York enters No 10 Downing Street via the garden entrance. The scene in which it appeared was before Edward VII's abdication, but the Humber was first registered 30 Dec 1936, which is after his abdication.

Revealing mistake: In various scenes before the Compass Rose is supposed to be fitted with radar, it's obvious the 'lantern' round the already fitted radar aerial has been removed and the aerial itself covered with a tarpaulin to simulate the ship in its earlier, pre-radar, state.
