This was the first appearance of the girls' father Victor. Interestingly, in this episode his last name was Halliwell. However, in later seasons it was revealed that Patty kept her maiden name and that Victor's last name was Bennett. Also, this was the only time that Tony Denison would play Victor. The role would be assumed in later years by James Read.
In the home video the girls watch on the couch at the end of this episode, Alyssa Milano plays their mother 'Patty Halliwell' in the clip.
On the final season DVD commentary, Brad Kern revealed that one reason that James Read replaced Tony Denison in the role as Victor Bennett was because Denison looked too much like a love interest rather than a father of the sisters.
Despite the magical protection the ring provides, Victor never wears the ring in any future episodes.
