The plot of the 1975 psychological horror film The Reincarnation of Peter Proud narrates the philosophical concept that the essence of a person continues to live in another physical form or body after biological death, a topic that perfectly fits into the supernatural and occult-loving 1970s. While sleeping, college professor Peter Proud (Michael Sarrazin) starts having some nightmares about a stranger’s murder by his girlfriend Marcia (Margot Kidder), followed by a series of recurring visions about some fragments of his life. Gradually, Peter is more and more drawn to an unknown place and starts feeling restless so he decides to visit it and the pieces of this mysterious puzzle start to stack together, one by one.

The film was based on a novel of the same name written by Max Ehrlich and, as the main cast became public knowledge, the film rights were immediately bought - even before the novel was published. The same writer joined the team and the film was directed by J. Lee Thompson. Los Angeles Times called it “riveting” and it was headed for a remake in 2009 by a very famous Se7en duo - the director David Fincher and writer Andrew Kevin Walker but, as of 2018, The Reincarnation of Peter Proud is listed as “in development”.
