Eleventh Doctor
The Eleventh Doctor is an incarnation of the Doctor, the protagonist of the British science fiction television series Doctor Who. He is played by Matt Smith in three series as well as five specials. As with previous incarnations of the Doctor, the character has also appeared in other Doctor Who spin-offs.
Within the series' narrative, the Doctor is a centuries-old alien Time Lord from the planet Gallifrey who travels in time and space in the TARDIS, frequently with companions. At the end of life, the Doctor regenerates; as a result, the physical appearance and personality of the Doctor changes. Smith's incarnation is a quick-tempered but compassionate character whose youthful appearance is at odds with his more discerning and world-weary temperament. Preceded in regeneration by the Tenth Doctor (David Tennant), he is followed by the Twelfth Doctor (Peter Capaldi).
This incarnation's main companions included Amy Pond (Karen Gillan), her husband Rory Williams (Arthur Darvill) and the mysterious Clara Oswald (Jenna-Louise Coleman).
