Bloody Mary is a 2006 horror thriller film written and directed by Richard Valentine and starring Jaason Simmons, Kim Tyler, Matt Borlenghi, and Cory Monteith.
Playing what the others call "The Mirror Game", she releases the vengeful spirit and is snatched away.
When Nicole is reported missing, her writer/reporter sister Natalie (Kim Tyler) decides to investigate on her own.
Near the end, almost all of the main characters are dead except for Natalie, who discovers that Bloody Mary is actually her mother.
[1] Steve "Uncle Creepy" Barton of Dread Central rated the film 2/5 stars and said of the film: "there's ... some good acting, killer sound design, spooky ghost effects, and a decent amount of nudity and gore.
