Majel Barrett's last appearance on TNG as Lwaxana Troi. She would make three further appearances in Star Trek: Deep Space Nine (1993), and still continue to do the voice of the Enterprise computer.
Split-screen shots against a blue screen were used to allow people to interact with the wolf, which, although trained, was still dangerous. Kirsten Dunst petted a stand rather than the wolf, with the animal matted in later. The wolf's growl was achieved by giving it a lick of a meaty bone, then filming its reaction when a trainer moved as if to take it.
The first and only appearance of Ian Andrew Troi, Deanna's father.
Hedril is played by an 11 year old Kirsten Dunst, a year before she became famous with Interview with the Vampire: The Vampire Chronicles (1994).
Marina Sirtis performed her own stunt when she seems to jump off into space. She leapt off a blue-screened platform onto an air mattress. This was then matted in with the star field and corridor walls.
