equaling one minute of screentime). To fill the gap, the sequence of Gwyllm discovering music was quickly written as a five-minute insert by Joseph Stefano. For this, the then-new Glenn Gould recordings of the Bach preludes were used, which were performed faster than anyone had done them before. The scene used three different preludes. As it opens, Gwyllm plays the Prelude and Fugue No. 2 in C Minor. Most of the conversation with Mathers uses Prelude and Fugue No. 5 in D Major. When he says "I shall stop soon anyway," he begins Prelude and Fugue No. 1 in C Major. The start of Act Four, showing Gwyllm's vengeful rampage against the mine, was removed. Originally, Gwyllm kills Wilks and his deputies, then proceeds on to the mine. The gatekeeper sees him coming, enveloped in a bituminous aura. Mr. Caradoc sets off the disaster whistle just as Gwyllm reduces him to smoldering ashes. Gwyllm then places a box of dynamite at the pit entrance, igniting the fuse with a burning glance. Emlyn, one of the trapped terrified miners, attacks him with a pickaxe and is flattened by a burst of kinetic force. Gwyllm then becomes translucent, evolving beyond the need for vengeance and abandons the burning fuse to walk back to Mathers' Lab. Robbart, another miner, stamps out the fuse. Gwyllm later tells Cathy his ghostly translucence is evidence of his further evolution: "I can now live by photosynthesis of pure light." The ABC censor, Dorothy Brown, objected to the Darwinism and promotion of evolution inherent in "The Sixth Finger". One of the earliest deletions from the script was a speech by Prof. Mathers on the subject: "In the short span of nine months, every human embryo passes through a million years of its previous evolution, from protoplasm to fish to amphibian to furry ape with a tail to man. I'm experimenting with a means of continuing this process in the same lifetime." – the dialogue foreshadowing the fate Ellis St. Joseph had in store for Gwyllm once Cathy pulls the lever on Mathers' machine, reversing his evolution. As originally scripted, Gwyllm devolves into the protoplasmic form of a jellyfish. However, ABC executives would only allow him to regress to the stages of early man, due to concerns that religious viewers who did not accept the theory of evolution would be offended.
