When this film was released in 1961, I remember the ads saying this film was for "Adults Only". (The MPAA rating system didn't exist then.) A film about four soldiers stationed in Germany who gang rape a 16 year old girl and the trial that followed was pretty heavy stuff for audiences back then. I recently saw the film on Turner Classic Movies, and it still holds up very well. It is still startling and powerful, even without nudity and foul language, which should show Hollywood it can be done. You can be "adult" without being unnecessarily vulgar or obscene. As it stands, I would still give this film an "R" rating today.
And, of course, there is the memorable title song, sung by Gene Pitney, which accounted for the film's only (surprisingly) Oscar nomination. Even that lost out to the syrupy "Moon River" from "Breakfast at Tiffany's".
My one complaint about Turner's presentation was with the film's aspect ratio. Instead of showing a widescreen version, they showed a full-frame version with the framing "squeezed" so that faces were somewhat elongated and cars appeared "stubby" and compacted. This became very annoying. Even a pan & scan version would be better than this.
Nonetheless, for sheer power, as well as excellent acting by Kirk Douglas, E.G. Marshall, Christine Kaufmann, and a very young Robert Blake, I highly recommend "Town Without Pity".
