This was the only time the name "Doctor Who" was used in the title of a serial on-screen (although Episode 5 of "The Chase" was titled "The Death of Doctor Who" on-screen and at the end of "The Gunfighters", the caption read "Next Week Doctor Who and the Savages"). Although it was common in production paperwork to prefix "Doctor Who and..." to the story title at the time, the prefix was usually dropped when the director ordered the titles from the captioning department for transmission. However, this was not done for this particular story.
