Edited for Syndication: Ever since the show left its original networks, the theme song was cut down to 45 seconds in the United States. The Disney Channel used to run this in syndication with the opening played in full, but this hasn't happen since then, not even when the show was put on Netflix.
Hey, It's That Voice!: Emily Hart (Melissa's younger sister, who recurred in the main show as Sabrina's bratty cousin, Amanda) voices Sabrina while (as mentioned above) her big sis voices Hilda and Zelda. Nick Bakay once again voices Salem as he does in the main show and Cree Summer is Chloe.
Bill Switzer, the voice of Harvey and the only actor who stayed for 'Sabrina's Secret Life'', also did Eli Moon.
In Mexico, Italy, and Poland Sabrina was Wanda. In Hungary, Sabrina was Rarity.
The Other Darrin: Due to Melissa Joan Hart and Buena Vista no longer producing the series, the voice actors in Sabrina's Secret Life were all changed, except for Harvey, who kept his voice from the first animated series.
Recycled Script: One episode had Sabrina, out of jealousy of a better swimmer, accidentally turning herself into a fish, and she could only turn back if Harvey kissed her; this same storyline was done in the sitcom's comic book. This was also the plot of one of the sitcom's tie-in novels.
