Start-News is reporting that Kristen Johnston has come aboard the cast of Vamps.

The film follows two female vampires (Alicia Silverstone and Krysten Ritter) in modern-day New York City who are faced with daunting romantic possibilities. Amy Heckerling (Clueless) has written the screenplay and she will also direct this film.

Kristen Johnston is going to play a mother who thinks something is askew when her son brings one of the female vampires home to meet here.

The film is set start production next week in Detroit.
