Two Men in Manhattan (1959) review

Fèvre-Berthier, the French delegate to the United Nations, goes missing and Moreau (Melville), a journalist for Agence France-Presse, is given the task of locating where he is and finding out whether or not he had a mistress, so he takes along unethical booze bag photographer Delmas (Pierre Grasset) to prowl the streets of New York City.  The script isn't exactly the tightest - it's just the two men interviewing pretty ladies of various professions (an actress, a jazz singer, a dancer, a call girl) and visiting famous locations (The Mercury Theater, Capital Records) - and some of the acting (and dubbing) is iffy, but it allows the director to indulge in his obsession with the United States, clearly reveling in photographing all those blinking neon lights and capturing that seedy "underworld" feeling of American noirs.  The last act, with Delmas going rogue and taking incriminating photos of the deceased diplomat (which Moreau tries to stop), reinforces the idea that you can be fascinated with other cultures ... but you should try to defend the reputation of your own country.
