Barack Obama

Barack Obama was the President of the United States of America in the late 2000s. He was making a publicized speech on the recession when he was, like everyone else on Earth, turned into a copy of the Master before being returned to normal with the rest of the human race. (DW: The End of Time)

Behind the Scenes

 * Barack Obama presumably took over from President-Elect Arthur Coleman Winters. (It has long been established that the US presidency in the "Whoniverse" does not coincide with that of the real world. Under US law, the death of Winters in DW: The Sound of Drums would not have been followed by a new election as might have occurred for a UK or Canadian prime minister; this suggests that, in the Doctor Who universe, Obama was likely elected as vice-president.)
 * Barack Obama was played by a stand-in whose face was not seen, but can be seen wearing glasses during his transformation scene. A soundclip of the real Obama can be heard as he begins his speech.
 * Barack Obama is the first living real-life American president to be seen on a televised Doctor Who serial.
