1977 horror
he Strange Possession of Mrs. Oliver is a 1977 American made-for-television horror film directed by Gordon Hessler and starring Karen Black, George Hamilton, Robert F. Lyons, Lucille Benson, and Jean Allison. The teleplay was written by Richard Matheson. The film first aired on NBC in 1977
Its plot follows a bored housewife who takes on an alternate persona that starts wreaking havoc on her life. Karen Black plays the title role, a dowdy, downtrodden housewife plagued by recurring nightmares of funerals, black flowers, fires, and a woman called Sandy. Seeking an escape from her stifling lifestyle and dull husband, who only wishes her to have a baby, Black dons a low-cut red blouse, blonde wig, garish makeup, and a new identity. She is also compelled to buy a house in a beach community where it would appear a woman who looks just like her once resided - before her tragic demise.
It turns out that the woman Black pretends to be may actually exist--and may have more than a passing knowledge of the occult.
