24 hours in A&E is a documentary that follows multiple storylines over the course of 24 hours in an emergency department. It uses a fly on the wall documentary style to film subjects without interference. Camera work includes close-ups during interviews, high angle shots to show the hospital activity, and over the shoulder shots of doctors helping patients. Sound design incorporates ambulance sirens, beeping medical equipment to convey emergencies, and a male voiceover with a Cockney accent setting the location. Editing employs montages, zooming to show patient pain, and narrow depth of field during interviews.
