Donna Noble is a fictional character in the long-running British science fiction television series Doctor Who. Portrayed by British actress and comedian Catherine Tate, she is a companion of the Tenth Doctor (David Tennant). Originally appearing in the closing scene of the show's 2006 series and as a special guest star in its following Christmas special, "The Runaway Bride", Tate was not expected to reprise her role as Donna. For the programme's third series (2007), the Doctor travelled alongside medical student Martha Jones (Freema Agyeman). However, Tate expressed interest in returning to the role, and returned to play Donna for the duration of the fourth series in 2008,^[1] and in a subsequent 2009-10 Christmas and New Year's special.^[2][3]
