The Silent Witness cast has evolved dramatically over three decades, but the team walking into the Lyell Centre in 2026 looks markedly different from the one that first appeared in 1996. With season 29 premiering in February 2026, viewers are keen to know exactly who is still on the case and which new faces have joined the forensic unit.

Who played which character in Silent Witness?
Matching actors to their characters can be confusing given the number of cast changes over the years. Here is a clear guide to the most important roles.

Jack Hodgson — David Caves
David Caves joined in series 20 as Jack Hodgson, a forensic scientist. His character later married Nikki Alexander, cementing their on-screen partnership.
Harry Cunningham — Tom Ward
Tom Ward played Dr Harry Cunningham from series 6 to 15. He was a core member of the forensic team for nearly a decade.

Who is in the Silent Witness cast for 2025?
The 2025 cast of Silent Witness (season 28) featured the same core group that continues into 2026. Emilia Fox, David Caves, Maggie Steed, and Francesca Mills were all present.
