Stephen Moore - known as the voice of Hitchhiker's Guide To The Galaxy's Marvin the Paranoid Android - has died aged 81.

He also played Adrian Mole's father on TV, and the dad to Harry Enfield's grumpy teenager Kevin.

Hitchhiker's producer and director Dirk Maggs said Moore was the "most sweet, charming and affable of men".

It is perhaps ironic that the vastly experienced, smooth as silk, inherently funny stage actor Stephen Moore, who has died aged 81, should be remembered mostly for voicing a robot, the paranoid android Marvin in the original radio series of The Hitchhiker’s Guide to the Galaxy. Douglas Adams’s hilarious science-fiction adventure began in 1978 and Moore stayed with it through four more series, the television show (still just the voice), the records and the audio books.

In a general sense, he was the voice of the show, as he picked off other roles when something different was needed – these included a mouse, a whale, and the ruler of the universe – and recorded the entire run of Hitchhiker books, on his own, for EMI. But even just vocally his range was considerable, as demonstrated in his regular appearances on BBC Radio 4’s Poetry Please, or his leading roles in radio versions of Madame Bovary (with Nicola Pagett and Roger Allam), Dostoevsky’s The Idiot and Marlowe’s Dr Faustus.
