The area between the supermarket and the office blocks is all that remains of the original studio, which has been much reduced in size and usefulness to production companies as a result. Elstree Studios were more recently used for the popular TV series "Who Wants to Be a Millionaire?" and "Big Brother", as well as several major feature films. The "Inspector Morse" TV series' production offices were based in the studios and, although the series was supposedly set in Oxford, several exterior locations (banks, shops etc.) were filmed in the streets of Borehamwood.
