the story in this movie be fairly implausible b grade stuff and but the script call for a creepy guy to play the lead and and in 1940 and that mean peter lorre . and peter be at his creepiest in this one a island owner stephen danel and who get prisoner parole to his custody to work at his island diamond mine . upon arrival the parolee discover that they be slave mine worker that can be beat or kill at the whim of danel . only two thing seem to have it bad off than the slave while danel wife and and monkey . monkey tick him off so much that his violence towards them probably lead to the only meat the slave get . lorre be perfect in his role here and and creep up the screen in industrial strength fashion . although the script be not casablanca caliber and the editing be very tight and there be no wasted scene . this be a very watchable story and but i be not sure what niche this movie fill . too long for a short subject and and too short for a feature length film and i be not sure how this be market to theater . i just catch this for the first time on a late night or early morning tcm showing . lorre fan will not want to miss this one if they haven not see it .
