A far-fetched crime story is overshadowed by extensive use of the photogenic Belvedere Castle in Central Park as the location for a solid shootout with police that climaxes this "Naked City" segment.
Paul Spencer, an itinerant young actor who IMDb identifies with just two screen credits, typifies a no-name cast, hamming it up as a maniacal criminal who has a lowly job working at a bank but insists on living the high life. He commits apartment robberies by kidnapping and impersonating milkmen, which sounds silly as a plot device and is.
Similarly, Spencer steals a 44 magnum from a gun collector's apartment, just in time to use it to threaten cops (or kill them) faster than you can say Dirty Harry, a gimmick commanding its own special sound effect. The token glamorous blonde with whom Paul has a ritzy restaurant date is played by Dorothy Dollivar, as obscure an actress as you can find, again with only two minor IMDb credits.
But the well-photographed views of the Castle, being used as a weather station, with a talkative weatherman taken hostage by the killer, stands supreme.
