Casualty is set to deliver a gripping Christmas episode as the BBC drama has unveiled first look images and announced a star-studded guest cast. The festive special, titled All I Want for Christmas , is described by the BBC as "a tribute to the miracle of blood, brought to life with all the tension and emotional depth that Casualty delivers so well". This Christmas special will see the ED team working tirelessly through the holiday season, only to be confronted with a critical shortage of emergency blood supplies.

Elinor Lawless's character Stevie is depicted fighting to save her patients' lives, while Michael Stevenson's Iain takes dangerous measures to prevent the hospital from running out of blood. Breaking away from its traditional format, this latest episode of Casualty follows in the footsteps of other notable episodes, including last year's homage to 75 years of the NHS , reports the Mirror . The forthcoming special is set to incorporate real-life accounts from individuals whose lives have been affected by blood donation in the UK, alongside interviews with the essential workers operating the national blood service.

In one released image, we see Stevie clutching a blood bag, standing solemnly in front of a Christmas tree, while another photo captures Iain with an expression of concern as he sits in the driver's seat of an ambulance, with festive lights glimmering in the distance. New images have been released showing paramedics Jacob (played by Charles Venn) and Teddy .
