Critical is one story, in one place, in one hour – a real-time medical and emotional roller-coaster ride in which every second counts during the most life-threatening hour of a patient’s treatment. The real-time nature of the drama takes the sense of realism to genre-defining levels, transporting the viewer from the airy atriums of a gleaming new hospital to the inner space of the human body.

Creator Jed Mercurio and actors Lennie James and Prasanna Puwanarajah talk about the show at BAFTA 195 Piccadilly. Recorded on Monday 16 February 2015.
