Dementia 13 is Fancis Ford Coppola's first feature film for which he is credited as the sole director. His few prior directorial outings were in the vein of sexploitation as a team member. So this film offers a glimpse into the chrysalis of his career. It's centered around a rich dysfunctional family, a mother and her 3 grown sons, who gather yearly at their Irish castle in remembrance of a sister who drowned at an early age in a pond on the property. With a large inheritance on the line, rumors of ghosts, a domineering matriarch who doesn't care for her sons' choices in women, a conniving daughter-in-law, and people going missing there's got to be some dementia somewhere. But the 13 is something of a mystery. Despite a hodgepodge script Coppala's embryonic direction has alluring edge. The cast includes Patrick Magee (Clockwork Orange) and William Campbell (Star Trek). As in many a Roger Corman production creative graphic/animated titles elevate the artistic element.
