directed by Richard Fleischer
With a running time of just over an hour it's really very short and doesn't spend much time on character development or in invoking any sense of dread, existential or otherwise.
There's actually a fair bit of comedy, some of it unintentional. The film actually tries to make us believe that a Japanese World War Two war criminal would attempt to hide out in a Chinese American residential area and NOT be detected by any of the people living therein.
This makes about as much sense as thinking that a German Nazi war criminal would CHOOSE to live in a Russian-Jewish American neighborhood and move around with no problems.
Perhaps to outsiders every East Asian looks the same or every European looks the same but people within those groups and the hundreds of smaller groups that comprise them have no problems distinguishing among each other. They've been doing just that for hundreds or even thousands of years!
