* DuelingWorks: With Creator/ABCFamily's ''Series/TheLyingGame.'' It lost.
* FakeAmerican: Gemma, played by British actress Tara Summers (''Series/BostonLegal,'' ''Film/WhatAGirlWants''). And in spite of her very "Sunnydale"-connected handle, that's her real name.
* FakeGuestStar: Zoey Deutch as Andrew's daughter Juliet appeared in 18 episodes but was only recurring.
* LifeImitatesArt: Like Siobhan, Creator/SarahMichelleGellar really did become pregnant in the course of the series (which would have been problematic for the series had it been renewed -- and may have been partly the reason why it wasn't).
** In a 2023 interview, Sarah Michelle Gellar revealed that her pregnancy was part of the reason she refused to do a second season.
* PlayingTheirOwnTwin: Creator/SarahMichelleGellar as Bridget and Siobhan.
* ProductionNickname: Staff refer to Bridget pretending to be Siobhan as "Shivette."
* WagTheDirector: One of Creator/SarahMichelleGellar's conditions for doing the show was that there not be a MusicalEpisode, as she didn't enjoy the preparations for "[[Recap/BuffyTheVampireSlayerS6E7OnceMoreWithFeeling Once More, With Feeling]]".
