Abby

One of the strangest, wildest, and weirdest blaxsploitation movies, Abby is an African-American retelling of The Exorcist, with Carol Speed as the possessed title character. The chaste and devout wife of a reverend, Abby spends her time as a marriage counselor in her neighborhood parish. Through mind-boggling misfortune having to do with the accidental release of a vicious demon, Abby begins to exhibit odd behavior (giving out salacious marital advice in one hysterical scene) and a noticeable change in the vocal register. Transforming from the practically virginal naif into a sex-starved ghoul with a hyena's chortle, Abby takes off into the night of dance clubs and singles bars. Father-in-law William Marchall races home from Africa to perform the exorcism, but will he be too late?
