Something of a regular guest star in the worlds of Sherlock and Doctor Who, Zimbabwean actress Chipo Chung has three appearances across the two shows under her belt. First, Chung appeared as Chantho, the kindly alien assistant to Derek Jacobi's disguised Master, Professor Yana, in 2007 episode Utopia. Chantho memorably meets a sad end when electrocuted by the Master once he takes back control of his body. The next year, Chung returned to Doctor Who in a more villainous role, appearing as the devious Fortune Teller who tricks Donna Noble into changing her past so that she never meets the Doctor. Lastly, the actress can be seen in a blink-and-you'll-miss-it role as the presenter of a documentary on the mysterious army base Baskerville in Sherlock episode The Hounds of Baskerville.
