This time last year, Melanie Hill made her first on-screen appearance as clinical nurse manager Siobhan McKenzie in BBC1’s hospital drama Casualty.
Now, 12 months later, the maternal medic is at the heart of the action and a rock to colleagues in her role as acting clinical lead, while privately navigating the painful breakdown of her 25-year marriage to firefighter Rich Walker (played by Michael Keogh) following his affair with consultant Stevie Nash (Elinor Lawless).
“When I joined the show, I knew there was going to be lots of great stuff ahead for Siobhan,” shares the acclaimed actor, 63, in an exclusive chat with What to Watch. “I’ve been really pleased with the reaction from Casualty fans. I think they’ve taken to Siobhan, which is nice.”
This week, as the latest 11-part mini-series Public Property continues, Siobhan faces her toughest challenge yet. In Casualty episode Brace, Brace, Brace Shiv, as she’s affectionately called, is placed in a heart-wrenching predicament when her husband’s life is on the line.
