This is the first episode to be directed by Patrick Stewart, the second cast member after Jonathan Frakes to direct an episode.
This is the last episode to feature Data's cat, Spot, as a Somali cat. After this episode, the Somali was replaced by an orange short-hair tabby.
After the observation room's brief exposure to space, Data makes note of changes in the transparent aluminum of the windows, a reference to the same material that Montgomery Scott introduced as a bargaining chip in Star Trek IV: The Voyage Home (1986).
In one scene, Picard jokes that the Enterprise must have a poltergeist. In a subsequent scene, chairs in the Bridge Observation Deck are piled on the table, as in a scene in the movie Poltergeist (1982).
