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.
