Merlin is the archetypal wizard, Welsh and Celtic in origin but with connections across the water in Cornwall and middle Europe, and, of course, the Arthurian legends. The powerful wizard is portrayed across folklore with many magical powers, including the power of shapeshifting, and is well-known for being King Arthur's mentor, ultimately guiding him towards becoming the king of Camelot. In this documentary, we take a deep dive into the fantastic world of Merlin and his influence in today's society.
