The Demon Headmaster was a massive hit in the mid-1990s which saw Hardiman play the sinister schoolmaster who used the power of hypnosis to enact his evil schemes

Actor Terrence Hardiman, best known for playing the title role in the CBBC series The Demon Headmaster, has died at the age of 86, his agent has said.

His death was announced ‘with great sadness’ by Scott Marshall Partners, which said he was a ‘beloved client and much-loved stage and screen actor’. 

He is survived by his wife Rowena and his two children. 

Hardiman also appeared in TV series such as The Crown, Wallander, Doctor Who and Prime Suspect.

The Londoner narrated hundreds of audiobooks, too, including series by the likes of Colin Dexter, Anne Perry and Ruth Rendell. 

But it was The Demon Headmaster and his trademark tinted glasses that made Hardiman a household name. 

The series was a massive hit in the mid-1990s which saw Hardiman play the sinister schoolmaster who used the power of hypnosis to enact his evil schemes.

The plot was based on the series of books written by Gillian Cross. 

Speaking in 2019 about originally taking up the role, Hardiman told Radio Times: ‘I thought, ”What a horrible character. How lovely. A real villain of a piece. Why not?”’

He said he had ‘no idea’ it would become such a success, adding: ‘I started to be recognised in the street, especially as I lived near schools around here, in North-West London. 

‘And there were people – youngsters – looking at me, and shouting out at me, and making fun of me, which is very healthy. It stopped me being too grand!

‘But then the slightly more remarkable thing, I found, was that it wasn’t just children who were watching. It was parents and other people, too.’ 

Hardiman returned to the series for a cameo appearance when it was rebooted in 2019.

Journalist Morgan Jeffrey, who interviewed Hardiman in 2019, tweeted: ‘Terrified a generation as the Demon Headmaster, but could not have been more of a good-natured gentleman in real life. 

‘It was such a thrill to speak to Terrence in 2019 when he made a cameo appearance in the Demon Headmaster revival – he was so clearly delighted to have made such an impact, delivering those ‘safe scares’ for young viewers at a formative age.’

One fan wrote: ‘He terrified an entire generation of children in The Demon Headmaster. What an icon.’
