Taste the Blood of Dracula (1970) or
Father Doesn't Always Know Best.
In the fifth installment of Hammer Films’ Dracula series, director Peter Sasdy and screenwriter Anthony Hinds (as John Elder) visit the theme of corruption from the older, patriarchal generation in conflict with the youth, themes Sasdy would revisit in his script for Twins of Evil, his final Karnstein trilogy story. Count Dracula himself undergoes an unusual change as he becomes an anti-hero, removing three of society's hypocritical leaders. To do this, he sets their children against the fathers in a revenge orgy of spilled familial blood and terror.
