Character & Cast

John is Assistant Turnkey of the Marshalsea Prison, where his father, Mr Chivery, has been Head Turnkey for many years. John takes everything extremely seriously, but especially his passionate and undying love for his childhood friend, Amy Dorrit. His moods change wildly from day to day depending on whether he's had an encouraging or discouraging sign from Amy. However, despite being somewhat angst-ridden, he's a truly kind and magnanimous soul who always looks out for others.

Russell's television highlights include My Family and Other Animals, Silent Witness and Holby City.
