Anjli Mohindra isn’t new to the Doctor Who universe. Between 2008 and 2011 she played Rani Chandra in the much-loved spin-offseries The Sarah Jane Adventures. “It was at that point that I became a Who fan and fell a bit in love with it all,” says Anjli. “So to be asked to do an episode of Doctor Who was very exciting because I wasn’t sure it would ever happen.”
