Sheila Reid (born 21 December 1937) played Etta in the Doctor Who story Vengeance on Varos. Nearly 30 years later, she played Clara Oswald's gran in The Time of the Doctor. She is thus one of the very few actors to have appeared in both production "regimes" of Doctor Who — the one that began in 1963, and the one from 2005.
Reid is best known outside of the DWU for playing Madge in Benidorm.
