From the mid-1950s to the early 1970s, wild, idiosyncratic crime movies were the brutal and boisterous business of Nikkatsu, the oldest film studio in Japan. In an effort to attract youthful audiences growing increasingly accustomed to American and French big-screen imports, Nikkatsu began producing action potboilers (mukokuseki akushun, or "borderless action") modeled on the western, comedy, gangster, and teen-rebel genres. This bruised and bloody collection represents a standout cross section of the nimble nasties Nikkatsu had to offer, from such prominent, stylistically daring directors as Seijun Suzuki, Toshio Masuda, and Takashi Nomura.
