This movie was made at Viking Studios which was located in St Mary Abbots Place, a quiet cul-de-sac off Kensington High Street in central London. The studios were behind the facades of houses whose address was 1-5 St Mary Abbots Place. The houses, like all the others in this short street had the pleasing aspect of all being built in different styles. This was a boon for filmmakers on low budgets as it meant they could create the illusion of filming in different places without ever leaving the street. In "I'm a Stranger", John Kelly walks past number 5, knocks on the door and enters number 3 (actually a door into the studio). Later, Greta Gynt tells James Hayter (who comes to her assistance) that her car has broken down. In reality, they're across the road from the studio. When she and James Hayter drive off, they're heading towards the end of the cul-de-sac. They stop upon discovering their stowaway and are, in fact, outside number 2 - which is where they started. Their stowaway asks to be taken to 'Dr. Westcott, number one Oxley Street'. They oblige and arrive at 1 St Mary Abbots Place, just across the road and another door into the studio.
