Overview
Blood Legacy (also called Legacy of Blood and Will to Die) is a 1971 horror film directed by Carl Monson and starring Rodolfo Acosta, Merry Anders, Norman Bartold, John Carradine, and Faith Domergue.
Synopsis
In this 1971 effort, Christopher Dean (John Carradine) has died; his four adult children Greg, Veronica, Johnnie, and Leslie, and their spouses, as well Christopher's longtime three servants have been called to the mansion to hear Christopher's previously taped last will. The servants are to receive a salary of $500 a month as long as they stay on; the children are to receive equal portions of the $136 million balance of the estate; however, if any die, the remainder will go to the survivors. If all of the children die, the servants inherit what is left. The children must for some reason stay in the deceased's house for one week in order to inherit. In this taped message, Christopher makes plain that he has no affection or respect for his four offspring; he advises them to run away from his offer if they have any virtue.
The killings begin promptly with the murder of Mrs. Greg Dean's dog, proceed to the decapitation of the police officer called about the incident, and continue until one individual survives. The terms of the will are such as to cast suspicion on any of the parties present. The surprise, and illogical, twist is who conducted the killings and why.
