Casualty to celebrate its 30th anniversary with a one-shot special
The hour-long episode will be filmed using a single camera all in one take to mark the special occasion.
To create this, the mobile camera covering A&E will be required to be cable free and will also have to cover action from inside a moving ambulance. The sound will be achieved with 40 hidden radio microphones and five boom operators, disguised as part of the set.
The episode will mostly focus on Duffy mentoring two teenage girls, Chloe and Diamond, who are being shown around the department for work experience, but will also include the series' regulars.
