- The original Blue Lamp was transferred to the new Paddington Green Police Station and stands there today. It has recently been restored.
- The producers obtained full cooperation from the Metropolitan Police (the first movie to do so) and were, therefore, able to use the real-life Paddington Green Police Station and New Scotland Yard for their location work.
- Police Constable George Dixon's (Jack Warner's) comment about the missing dog, "You ought to have called him Strachey", is a reference to the then Minister for Food, John Strachey. Strachey was in charge of rationing and, like the dog, was "accused" of stealing food from the people.
