Is There A Better Voyeuristic Movie Than "Peeping Tom"

I see the director of Peeping Tom, Michael Powell, although he lived to 1990, didn't seem to make many films after 1960. He made "Age of Consent" in 1969 -- which sounds more provocative than it is, given that the "girl" in the plot having a "relationship" with James Mason (always good at playing a creep) was played by actress Helen Mirren, age 24 at the time -- though young enough looking to suggest a teenager?

As far as Hitchcock goes, I think Rear Window is more concerned with the subject than Psycho.
