She's a serial killer with a secret. Sci-fi fave Amy Acker (Angel, Dollhouse) guest stars on the Feb. 10 episode of NBC's fairy-tale cop drama Grimm as a spiderwoman who seduces and slays a string of Portland men by sucking out their organs and leaving their bodies mummified. Don't be looking for some feminist statement here. "This is not one of those revenge-against-men-type stories," Acker says. "She's a black widow who is facing a very difficult inner struggle. She's doing what she must to survive." To attract her victims, the character goes undercover in various hot disguises, then when it's time to do the nasty, suddenly sports fangs, extra arms and lots of body hair.
You can also find Acker on the March 4 episode of that other fairy tale series, ABC's Once Upon a Time — as a love interest for Grumpy the dwarf!
