10 Doctor Who Voice Talents You've Never Even Noticed
6. Alexander Armstrong (Mr Smith)
A 'pointless' entry? Maybe not, because this is from the spin off series The Sarah Jane Adventures in which comedian and gameshow host Alexander Armstrong took on the role of super computer Mr Smith. Living behind the chimney in Sarah Jane's attic, Mr Smith would advise Ms Smith on all things alien as well as playing himself a little fanfare whenever he appeared. Now famous for the addictive gameshow Pointless, Alexander Armstrong is also known for his comedy double act with Ben Miller. Armstrong also has some considerable musical talent which he is never afraid to show off - he's the leader of a band which performs a range of jazz and rock classics, none of which were included in The Sarah Jane Adventures, more's the pity. He got to cross over to the mothership and lend his voice in Doctor Who when Mr Smith appeared in Tenth Doctor's 2008 two-part finale The Stolen Earth and Journey's End and he later appeared on screen as Reg Arwell in the 2011 Christmas Special The Doctor, The Widow and The Wardrobe.
