The World Was His Jury (1958)

Revealing mistake: When a yellow cab pulls up to the curb, it is obvious that the street is part of a studio backlot and not a real city street because the businesses have no names. The sign outside one building says simply "Tobacco." The diner has only the word "Restaurant" painted on its windows. Another business has no identification other than "Fish and Poultry" painted on its window.
