Julius Silverstein was a wealthy Jewish businessman and collector of rare artefacts with his own private museum. He purchased a deactivated robot Yeti from Professor Edward Travers, who had acquired it in Tibet in 1935. Forty years later, Travers — having succeeded in reactivating a Yeti control sphere which later vanished — went to Silverstein and requested that he return the Yeti, warning him of the danger. However, Silverstein refused to listen, and was killed by the reactivated Yeti soon afterwards. (TV: The Web of Fear)
Behind the scenes
