A well known soap star is joining the cast of BBC One’s Casualty for the medical drama’s new boxset.

Mark Womack, who is 65, played the role of DI Mark Malone in ITV’s Emmerdale in 2020. The character was a bent copper, who was eventually murdered by Dawn Taylor (Olivia Bromley).

The actor will return to soapland this Saturday, as Casualty’s new boxset Lethal Legacy hits our screens.

Still reeling from a devastating loss, the team must fight to survive as a suspected pandemic threatens to overwhelm the ED.

Release today, the dramatic new trailer for the 12-part mini series teases the hospital staff facing harsh truths as long-buried secrets resurface.

With a surge in patients arriving with an unexplained virus and the ED buckling under the strain, the army will be deployed to the hospital to keep the peace.

Mark Womack will play the role of domineering Colonel Jack Bard, whose powerful hold over his subordinates, and ties to Flynn Byron (Olly Rix), threaten to shake the bedrock of the ED.

When history begins to repeat itself, Flynn faces a past he believed was long behind him, while Stevie Nash (Elinor Lawless) and Matty Linklater (Aaron Julius) turn to an unexpected source of comfort. Also, a decision made by Matty pushes Dylan Keogh (William Beck) away from the son he’s only just started to get to know.

Meanwhile, Jodie Whyte (Anna Chell) uncovers a disturbing truth buried deep within a local estate and risks everything to expose it.

Trouble within the military casts a shadow, while strained relationships come to the fore as the team struggles to keep the ED afloat. With old wounds reopening, the team need to pull together – or watch everything unravel.
