The band playing at the Bronze is Darling Violetta, who later would provide the title theme for the Buffy the Vampire Slayer (1997) spin-off show, Angel (1999).
K. Todd Freeman (Mr Trick) auditioned for the role of Spike and was a front runner for the role alongside James Marsters.
The vampire seen dancing with Faith uses somewhat dated dance moves, harkening back to Welcome to the Hellmouth (1997) in which Buffy picks a vampire out of a crowd based solely on his out-of-fashion clothes. Joss Whedon had originally wanted vampires to wear clothing from the era of their human lives, but felt that this would make them less frightening.
Faith's needing to stake Kakistos with a more potent stake is consistent with the series treatment of older and more powerful vampires, as with The Master being impaled on a broken table in Prophecy Girl (1997) and the Turok-Han Vampire in Season Seven.
When Buffy asks Giles about the accuracy of her saying leprechauns aren't real, Giles responds with "As far as I know, yes." Marking the first instance of the running gag throughout both Buffy the Vampire Slayer (1997) and Angel (1999) referencing the ironic nonexistence of a magical creature in a world where most if not all other mythical beings do in fact exist.
