The realistic newspaper footage was shot in the Fleet Street offices of Express Newspapers and gives a vivid picture of the "old" London Fleet Street industry (most British newspapers have now moved out of this area, which was famous as a press centre). "Express" editor Arthur Christiansen plays himself in the film.
The scenes of the "Met Office" were filmed both outside and inside the Ministry of Defence Main Building in Whitehall. This access was remarkable. Those interiors were little changed until refurbishment of MOD after 2000.
In an early scene Jeannie is struggling with a Roneo stencil duplicator, saying it is "over-inking". The Roneo company threatened to sue the producers for the potential damage to the reputation of their products.
At about 45:20 into the movie the actress portraying Jeannie Craig (Janet Munro) steps from the shower and wraps herself in a towel. The image in the mirror at the right of the screen reflects her nude breasts. This movie was shown here in America in the early sixties. Although that type of scene was common in Europe; one wonders if the American censors deleted that portion of the movie.
