Andrew Sachs (born Andreas Siegfried Sachs) is a German-born English character actor who provided the voice of Skagra in the webcast/audio version of Shada, based upon a Season 17 Doctor Who story that was never completed. Sachs also played a non-DWU version of Professor Chronotis for the radio adaptation of Douglas Adams' non-Doctor Who novel Dirk Gently's Holistic Detective Agency.
Sachs is best known for playing the hapless Spanish waiter Manuel in the classic 1970s comedy series Fawlty Towers (1975, 1979) opposite John Cleese. In 2008, Sylvester McCoy suggested that Sachs would make the best replacement for David Tennant, soon to leave the role of the Tenth Doctor. Following the departure of Colin Baker from the role, Sachs had auditioned for the role of the Seventh Doctor in 1987, but McCoy was cast instead.
