Second Doctor
The Second Doctor is an incarnation of the Doctor, the protagonist of the BBC science fiction television series "Doctor Who". He was portrayed by character actor Patrick Troughton.
Eighth Doctor
The TV film did not lead to the commissioning of a revived television series, and while Eighth Doctor stories continued in other media, "Doctor Who" did not air again on television until 2005. After this, footage and stills from the TV film would be used in later episodes "The Next Doctor" (2008), "The Eleventh Hour", "The Lodger" (both 2010) and "Nightmare in Silver" (2013). Edited archive footage in "The Name of the Doctor" very briefly shows the Eighth Doctor sharing an adventure with the Second Doctor (Patrick Troughton).
