Dr. Capel-Smith, appeared as the villain in "The Tale of the Guardian's Curse" he was portrayed by James W. Caroll.
He was a brilliant archaeologist and Egyptologist. Whom for many years was desperately searching for the sarcophagus of Mina the Guardian. He was mostly interested in finding the
Ring of Eternity. He believed that this ring would grant him immortality to live forever. Mina the Guardian's sarcophagus was finally found in the 1990's. He was certain that his brilliant colleague Professor James Dugan had found the ring. He then proceeded to break into his colleague's house. There he tore the whole place apart trying to find it. He was still inside/ when he saw Professor Dugan's children Josh and Cleo run inside blurting out loud that they had found it.
He knew his colleague possibly had plans to report and return the mummy to a proper museum in Egypt. Therefore he raced back to the museum. There he ran up to him and knocked him with a chloroform soaked rag. Next he dosed many of the crates in the museum basement with kerosene. making the place very flammable. Then later, he encountered Professor Dugan and his children in the museum basement. He told them that he did intend to use the ring for himself and told them that he drenched the crates in the basement with kerosene. So therefore if they did not give the ring to him he would light the torch and drop it. Then the whole museum would burn down with them all inside.
Cleo was convinced and sternly talked Josh into giving him the ring. He was about to leave them all inside and burn the museum down with them in it, because he didn't want the authorities to being tracking him for all of eternity. Cleo beckons him to at least show them if the ring even works. Getting excited he decides to try it out right away, he puts the ring on his finger and at first he glows in a pleasant blue aura. He claimed that he felt wonderful and that they were now gazing at an immortal.
Then suddenly, the Dugans all shieled their eyes. Then he suddenly begun to glow in a Green aura. He trembled and panicked. Then he said that he could not move and he instantly turned into a solid rock Egyptian statue. He got eternity all right... What else lasts for eternity more than a stone statue?
What he didn't know was that they also had the Elixir of Life. It turned out there was a curse because Dr. Capel-Smith only used the ring. So therefore, he was granted eternity in the form of an Egyptian stone statue. If he had poured some of the Elixir onto his finger before putting the ring on, then it would have worked properly.
