Back in '47, a gun was a roscoe, a private-eye was a Peeper, and murder was okay as long as nobody got hurt. In fact, anything was okay with this Peeper on the case because he wouldn't know who-done-it even if he done it himself.
Peeper is a 1975 American mystery comedy film directed by Peter Hyams, starring Michael Caine as Leslie C. Tucker, a bungling private investigator. A send-up of 1940s films noirs, Peeper was a box-office failure that jeopardized Hyams's career and almost prevented him from obtaining funding to produce Capricorn One.
