We expect much more of cult directors Arthur Ripley and Edgar G. Ulmer than this cheap-jack keep-the-flag flying item which is as poorly acted and scripted as it is bottom-of-the-barrel produced. And along with the movie's sparse production values, it's hard to separate who gives the worst performance. Almost everyone in the cast lacks charisma, but I guess the hammiest is German actor Ernest Dorian. Admittedly, he is given lines that would stump even Humphrey Bogart, but Dorian is also hindered by his mind-boggling casting as a Japanese infiltrator rather than a German spy! Alan Baxter is not much of a hero either, but it is a real shame to find a talented and normally charismatic player like Gertrude Michael cast as the heroine in this cheap-jack, dismal "D"- grade production. Available on a just-watchable Alpha DVD.
