Former “Buffy the Vampire Slayer” star and Playboy cover model (July, 2000) Charisma Carpenter is set to play identical twin sisters in director Hanelle Culpepper’s (How to Stand in Line for Star Wars) now-shooting in Los Angeles psychological thriller Deadly Sibling Rivalry.

The film follows the different paths estranged twins Janna and Callie travel after the accidental death of their beloved father. When an automobile accident leaves successful and happily married Janna in a coma, downtrodden degenerate Callie assumes her identity and quickly plots a way to keep her sister gone.

Carpenter, of course, made her name in Hollywood by being ridiculously hot and by playing bratty babe Cordelia Chase on “Buffy the Vampire Slayer” and its spinoff “Angel.” She also starred as gold-digger Kendall Casablancas on teen mystery show “Veronica Mars.”

As for the big screen—sort of—the 40-year-old stunner can be seen in director Jason Bourque’s upcoming survival-frightener Crash Site and the now available on DVD British thriller Psychosis.

Norwegian actress Ingrid Bolsø Berdal, best known for the 2006 survival frightener Cold Prey, is the first to join Famke Janssen’s coven of witches in Dead Snow director Tommy Wirkola’s Hansel & Gretel: Witch Hunters, a flash forward of the classic fairy tale that finds the siblings hunting down supernatural forces for profit.

Berdal’s character is described as being a ruthless “killing machine” under the command of Janssen’s head witch. Hot properties Jeremy Renner (The Town) and Gemma Arterton (Clash of the Titans) headline the 3-D Paramount Pictures film as Hansel & Gretel.

Hansel & Gretel: Witch Hunters rolls camera on March 7. It’s expected to be in theaters in June 2012.

Memphis-born stunner Clare Grant is set to star in Hatchet and Frozen director Adam Green’s pilot episode of “Sexy Nightmare Slayers,” a proposed web series from ArieScope Pictures and Comedy Central’s Atom.com.

Green tells Dread Central:

We have come up with something that is kind of like “Buffy the Vampire Slayer” meets Evil Dead II. We had total creative control so you’re going to be seeing stories filled with hot chicks, cool monsters, and lots and lots of monster goo.

We could make three more, we could make thirty more. It depends on how this one does and of course our availability at the time.

“Sexy Nightmare Slayers” stars Grant and Rileah Vanderbilt (Frozen) as half-naked angels sent from heaven to protect children from nighttime monsters. If picked up, the series—created by Green and Vanderbilt—will feature a variety of guest stars and directors.

Grant’s horror creds include After Dark’s The Graves, an episode of Showtime’s “Masters of Horror” (“Valerie on the Stairs”), and marriage to Seth Green. To see photos of Grant nude, go here.
