Actor Stephen Moore, who originated the woeful voice of Marvin the Android in the original 1978 BBC Radio production of Douglas Adams’ The Hitchhiker’s Guide To The Galaxy, dies at the age of 81. Ironically, it was another voice role, in a Czechoslovakian-made production of A Midsummer Night’s Dream in 1959, featuring only puppets, that started Moore’s screen career. He would later go on to play memorable roles in Rock Follies, The New Avengers, Solo, and The Secret Diary Of Adrian Mole. In 2010, he appeared as a war-weary Silurian elder opposite Matt Smith in the Doctor Who episode Cold Blood. Having played Marvin’s voice on radio in 1978 and 1979, and reprising the role for the 1981 BBC2 TV adaptation of Hitchhiker’s Guide, Moore returned to play Marvin again in BBC Radio’s early 21st century adaptations of the Hitchhiker’s Guide novels that weren’t directly based on the original radio series.
