In 1962, François Truffaut proposed a lengthy interview with Alfred Hitchcock, intending to publish it as a book. It wasn't until 1966 that "Hitchcock" appeared, becoming a seminal work in film literature worldwide. Truffaut later expanded the book, publishing a definitive edition in 1983, three years after Hitchcock’s death. This film details the creation of that book and explores the unusual friendship between the two filmmakers. It features previously unheard excerpts from the original interview recordings, including the voices of Hitchcock, Truffaut, and Helen Scott.
