El sonido de los tambores
"Last of the Time Lords", along with "Utopia" and "The Sound of Drums", are treated in several sources as a three-part story, the first such story in the revived series of "Doctor Who". However, Russell T Davies has said that he regards "Utopia" as a separate story, but notes that the determination is arbitrary. "Last of the Time Lords" was a subtitle proposed at one stage for a film version of "Doctor Who" that was in development from 1987 to 1994.
