John Ronald Simm played the Master in Utopia, The Sound of Drums, Last of the Time Lords and the two-part Christmas special The End of Time. In the The End of Time he played several members of the human race after they had been converted into the Master Race. Some of these humans included Joshua and Abigail Naismith, Sylvia Noble, Shaun Temple, Winston Katusi, Barack Obama and several reporters in the White House, Mr Danes, a Teenager, several other heads of military intelligence's such as UNIT and several other unnamed people.
Simm received second billing in the opening credits for both parts of The End of Time, making him the second villain actor in the history of the franchise to be so credited. The first was Eric Roberts, who also played the Master in the 1996 TV movie.
Simm previously appeared in the film Human Traffic and the TV series Spaced, but is probably best known for his role as Sam Tyler (interestingly named after Rose Tyler when the surname Williams was deemed unsuitable) in the BBC drama Life on Mars.
