Buffy l'ammazzavampiri

Spike's trademark coat cost $2,000 from a top fashion store. It was then run over repeatedly by a truck to give it that distressed look.

In nearly every episode presented in widescreen, there is crew/equipment visible and/or revealing mistakes. This is because the series was originally shot for 4:3 frame and these issues would not have been visible as the show was originally intended to be presented. As such, one should take much of the goofs reported on episodes as being conditional on applying only to the widescreen alternate version.

The sequence with the Mutant Enemy mascot, the little monster that goes "Grr Argh" at the end of all episodes, was changed for a total of six episodes: in "Becoming Part Two" (#2.22) it said, 'Oh, I need a hug." in "Amends" (#3.10) it wore a Santa hat and bells were jingling. in "Graduation Day Part Two" (#3.22) it wore a graduation cap. in "Once More With Feeling" (#6.07) it sang its "Grr Argh." in "Storyteller" (#7.16) it sang, "We are as gods." in "Chosen" (#7.22) it looked out at the viewers instead of looking straight-forward.

In the French and Spanish dubs of the series, Xander's name is changed to Alex.
