The vampire comedy from the Clueless director
Vamps tells the modern-day tale of two female vampires who live it up in New York until love enters the picture, when each has to make a choice that will jeopardise their immortality.
Silverstone will play one of the vampires opposite previously announced Krysten Ritter, who is making her first feature starring role and is about to wrap production on the comedy Killing Bono opposite Ben Barnes.
Production is set to begin in April.
