Outer Limits (TV) – "Sixth Finger" – Gwyllm Griffiths 12" Figure

David McCallum portrays Gwyllm Griffiths, a Welsh coal miner "thrust forward into our biological future" by Professor Mathers, using a a machine that compresses ten thousand years of evolution into the space of a few seconds.

Once the "self-generating force" of evolution is unleashed by the device, Gwyllm continues to evolve - his cranium expands, his hair vanishes, and he develops a sixth finger on each hand "for additional dexterity" - until he becomes the superintellect of a million years in our future, unable to relate to the human condition any more than we could relate to apes by comparison.

Gwyllm's bulbous-brained countenance is one of the The Outer Limits' most recognizable images, and The Sixth Finger, one of the series' most creative and provocative episodes.
