Charisma Carpenter is going postal…

The 46-year-old part Spanish-American actress and former Buffy The Vampire Slayer star is set to star in the sci-fi family drama Mail Order Monster, from director Paulina Lagudi and Jax Productions.

The film stars Madison Horcher as 12-year-old Sam Pepper, who lost her mother in a car accident, and her reclusive, quirky nature makes her an easy target for bullying. Realizing she’d had enough, Sam orders the parts to build a “Monster” from a comic book ad, and is finally able to get back at the bully. When Sam discovers her father Roy (Josh Hopkins) proposed to his girlfriend Sydney (Carpenter), she relies on her monster to keep her from getting a new mom.

Lagudi and Marc Prey co-wrote the film, which will go before cameras next month in Kentucky.

Carpenter, who starred on Angel, recently appeared in Criminal Minds: Beyond Borders and Lucifer.
