Sigourney Weaver has signed on to star opposite Alicia Silverstone and Krysten Ritter in writer/director Amy Heckerling’s vampire rom-com Vamps. Weaver will play the vampire queen responsible for turning Silverstone and Ritter’s characters into bloodsuckers.

I’m not sure what’s brought on Hollywood’s fascination with the older woman/younger girl dynamic (see Amanda Seyfried Dykes Out with Julianne Moore), but I’m digging it—although, not so much in this case.

Vamps centers on two New York based BFF vampires (Silverstone, Ritter) whose friendship and immortality is threaten when they each discover love. The film reunites Silverstone with her Clueless director.

Vamps is slated to begin production in April.
