From the murky depths can come the most extraordinary things. . . . Profoundly Disturbing examines the underground cult movies that have–unexpectedly and unintentionally– revolutionized the way that all movies would be made. Called “exploitation films” because they often exploit our most primal fears and desires, these overlooked movies pioneered new cinematographic techniques, subversive narrative structuring, and guerrilla marketing strategies that would eventually trickle up into mainstream cinema. In this book Joe Bob Briggs uncovers the most seminal cult movies of the twentieth century and reveals the fascinating untold stories behind their making.
