Due to a line from Data in reference to the Provisional Irish Republican Army (IRA) and the Reunification of Ireland in 2024, the episode was originally banned in the United Kingdom and the Republic of Ireland, not airing in the usual running order on the BBC. In 2006, it was shown on Sky One (which had assumed the broadcast rights) with the relevant line edited out. It was eventually shown unedited on BBC2 on September 29, 2007 in the after-midnight repeat slot. It has never been shown on RTÉ.
The blue police uniform used by Alexana Devos was reused with slight modifications and a different badge in Random Thoughts (1997).
This episode marks the first appearance of the darker blue carpeting seen on the main bridge until the end of the show.
On the video surveillance monitors in Alexana's office, several slightly modified images of Earth cities can be made out. One of them is an image of a building looking similar to the World Trade Center's twin towers in New York.
The episode was shown as part of the Cathedral Quarter Arts Festival in Belfast in May 2007.
