Michael Palin

Michael Palin is best known as one of the founding members of Monty Python's Flying Circus, but has also branched out into travel documentaries such as Around the World in 80 Days and Pole to Pole. Donna Noble's mother compared her daughter to him after the latter said she wanted to travel (DW: Partners in Crime).

Behind the scenes
Michael Palin turned down the role of The Eighth Doctor in Doctor Who: The TV Movie. It is unknown if it was because he was not interested in the project or because he was busy with other projects.
