Mike Colter (Evil), Raúl Castillo (Smile 2), Matt Frewer (Perry Mason), and Thomas Lennon (Reno 911!) round out the cast of horror film, The Casket Girls, which stars Gabrielle Union, Deadline reports.

The Casket Girls is inspired by true events involving a group of young women sent from France to New Orleans to become brides to French colonists in the early 1700s. They arrived with small chests, or “caskets” of their belongings, hence the name given by locals. According to legend, upon the girls’ arrival, the homicide rate in New Orleans rose dramatically, with stories of men drained of their blood. The girls were blamed and feared to be demons or vampires. For the city’s protection, the girls were imprisoned in the attic of the Vatican controlled Ursuline Convent, which still stands today in the heart of the French Quarter, locked away behind an impenetrable door and windows bolted shut by nails blessed by the Pope himself.

The film takes place in today’s world as Detective Shay Williams (Union) and her partner Galpin (Colter) become trapped inside the Ursuline Convent with a motley group (including Castillo, Frewer and Lennon) when the Casket Girls escape from their attic prison for the first time in over 300 years.

Lennon co-wrote the screenplay alongside Robert Ben Garant, with revisions by Keith Cooper (Anything for Jackson) & Justin Dyck (Anything for Jackson), who directed the film.

The Casket Girls will be played by Hazel Bartlett-Sais (Longlegs), Lucia Morris (Nobody Dumps My Daughter), Ana Pacheco (Seed), Talisa Mae Stewart (Are You There?), Haylie Hansen (The Chicken Sisters) and Charlotte Kavanagh (Grease: Rise of the Pink Ladies), with Jake Manley (The Order), Carolina Rolo (Grease: Rise of the Pink Ladies), and Yari Pernia (Christmas on 5th Avenue) rounding out the cast.
