Sarah Jane Adventures story The Wedding of Sarah Jane Smith. Tennant also appears in two animated serials The Infinite Quest and Dreamland. In 2013, Tennant reprised his role as the Doctor for the 50th anniversary special, "The Day of the Doctor", and will return to Doctor Who as the Fourteenth Doctor in 2023 for three 60th anniversary specials. Personality The Tenth Doctor speaks with an Estuary English accent, rather than the Lancashire dialect (Christopher Eccleston's own dialect) that the Ninth Doctor used, the Received Pronunciation of most earlier Doctors, or Tennant's natural Scottish English. David Tennant told SFX magazine in 2006 that Russell T Davies had asked him to drop his natural Scottish accent, because he felt "we'd like to not go for another obvious regional accent, because I suppose they'd done that".

All sticky-uppy". He has dark brown eyes and is perceived by most, including companions and other characters such as his future incarnation as "slim and a little bit foxy". His costume was unveiled on 27 July 2005. He generally wears either a dark brown (with blue pinstripes) or a blue (with rust red pinstripes) four-buttoned suit with a shirt and a tie, or a shirt and t-shirt, a light brown faux-suede duster coat (which he claims was
