French heartthrob Alain Delon made his US leading man debut in this adaptation of Zekial Marko's novel "Scratch a Thief" about an ex-thief in San Francisco trying to stay out of trouble but fingered for the murder of a Chinese storekeeper by the police sergeant (Van Heflin) who hates him. Meanwhile, the thief's shady older brother (Jack Palance) is in town, needing the kid's help in pulling off a job. Ordinary crime plot given amusingly jazzy, frenetic direction by Ralph Nelson, who sets the scene with a flashy nightclub drum solo that is crazy-cool. Screenwriter Marko really lays on the '60s-era jive talk, some of it mind-boggling, while Nelson's quasi-European handling gives the picture an arresting look in vivid black-and-white. Some of the interesting supporting characters include a fey platinum-blond punk (years ahead of his time), plus Ann-Margret as Delon's put-upon wife. The talky lulls are given a boost by the slangy dialogue, and the location shooting in San Francisco is a big asset. **1/2 from ****
