PRISONER OF JAPAN is a typical WW2 B-movie of the 1940s. It's low budget and dated, and yet it passes the time amiably enough and features some spy-themed hijinks between American and Japanese agents on a Pacific island. The cast was unknown to me but the writer/director is none other than Edgar G. Ulmer, who made the excellent BLACK CAT in 1935. PRISONER OF JAPAN isn't anywhere near the quality of that classic, but it's an acceptable potboiler regardless.
