Martin Scorsese, who has long been an admirer of Powell's works, has stated that this film, along with Federico Fellini's 8½, contains all that can be said about directing:
“I have always felt that Peeping Tom and 8½ say everything that can be said about film-making, about the process of dealing with film, the objectivity and subjectivity of it and the confusion between the two. 8½ captures the glamour and enjoyment of film-making, while Peeping Tom shows the aggression of it, how the camera violates... From studying them you can discover everything about people who make films, or at least people who express themselves through films.”
