Buffy the Vampire Slayer creator Joss Whedon has confirmed in an interview with Filmforce the influence of Night of the Comethad on his hit TV show.
I would like to make a movie that was one of these crappy, low-budget movies, that like the Romero films, had a feminist agenda, had females in it who were people, and had all the fun, all the silliness. Night of the Comet was a big influence. That actually had a cheerleader in it. With a title that would actually make people take it off the video store shelves, because it has to sound silly and not boring.
The full interview from June 2003 is split into 10 parts and can be viewed on the ign website.
