Kenneth Griffith (12 October 1921 – 25 June 2006) was a Welsh actor and documentary film-maker.
Born Kenneth Reginald Griffiths in Tenby, Pembrokeshire, Wales, six months after his birth his parents both left Tenby, going their separate ways and leaving Kenneth with his paternal grandparents, Emily and Ernest, who immediately became his mother and father. A lively rugby union scrum-half, he attended the local Wesleyan Methodist chapel three times every Sunday.
Griffths passed the Eleven plus and attended Greenhill Grammar School, where he met English literature teacher Evelyn Ward, who recognised his writing and acting talent. Before leaving school, his headmaster J.T. Griffth suggested that he drop the English "s" from his name as it was an anglicisation, which he did from that point onwards.
In 1937 he left school and moved to Cambridge, taking a job at an ironmonger's weighing nails. This lasted only a day and proved to be the only job he ever had outside of the acting world. He approached the Cambridge Festival Theatre for work, and at the age of 16 was cast by Peter Hoare as Cinna the Poet in a modern-dress version of Julius Caesar. He became a regular jobbing repertory actor,
