Gerald Flood

Gerald Flood (born on 21 April 1927 Portsmouth, Hampshire; died on 12th April April 1989) both played King John and provided the voice of Kamelion in The King's Demons. Technical problems with the Kamelion robotic prop made it not possible for Gerald Flood to appear regularly on Doctor Who as a voice actor for Kamelion. However, he did reprise the role in Planet of Fire and in a cameo in The Caves of Androzani.

Gerald Flood also portrayed Sir Richard Flashman in the BBC's popular 1971 television serial "Tom Brown's Schooldays". He died from a heart attack shortly before his 62nd birthday.
