Terrence Hardiman, born 6 April 1937 in Forest Gate, is an English actor whose career has encompassed stage, television, film and radio. He became widely recognised by younger audiences for the title role in the children's television series The Demon Headmaster, and is also well known to adult viewers for his portrayal of a Luftwaffe police officer in the 1970s drama Secret Army. His screen work includes appearances in high-profile films such as Gandhi.
Career highlights
Hardiman's acting work has been steady and varied, with long stretches of television work alongside stage commitments.

Across his career Hardiman was frequently cast as figures of authority: military officers, administrators, judges and headmasters. Reviewers and colleagues have noted his economical delivery, clear diction and an ability to convey control or menace through subtle facial expression and voice rather than broad gesture. Those qualities made him suitable for both period drama and modern settings.
