Un crimen por hora

Akira Kurosawa visited the set, meeting one of his main influences, John Ford.

The background scene of London outside Gideon's office windows is actually a miniature set rather than back projected film. This is revealed by the fact that the cars and buses crossing the bridge are clearly small models or toys. In fact in the opening shot of Gideon looking out of his office at night, the miniature is used on its own instead of inserting stock footage, and the model vehicles are particularly noticeable.

When title music plays "London Bridge is Falling Down" there is a full-screen picture of Tower Bridge.
