Kenneth's educational journey began at a grammar school in South Wales, where an English literary teacher introduced him to the world of plays by having the class read out parts. This unique approach resonated with Kenneth, and he found himself enjoying the experience immensely. As a result, he was selected to participate in a production of Richard II, a pivotal moment that would shape his future.
A local critic's glowing review, praising Kenneth's performance, sparked an unexpected interest in acting. Notably, this was during a time when Kenneth had never witnessed an actor or a theatre performance before. His school years came to a close at the age of 15, leaving him uncertain about his future plans.
Joining the army was initially considered as a viable option, as it would provide Kenneth with a sense of structure, a uniform, and a means of sustenance. Additionally, the possibility of being stationed in India was an attractive prospect. However, Kenneth opted for a different path, enrolling at Cambridge at the age of 15 and a half to work in an ironmongers.
Undeterred by his lack of formal theatre training, Kenneth approached the stage door of the Cambridge Theatre, armed with his notices and a determination to meet the producer. His persistence paid off, as he was offered a job at a weekly wage of £3. Kenneth's remarkable career would go on to span over 70 films, in addition to his work on two documentaries, which he researched and directed himself.
