DEVIL'S ISLAND proved an interesting change-of-pace for Karloff but one which, I agree, is hampered by its second-feature status: as it stands, potentially controversial issues like miscarriage of justice, as well as prison brutality and corruption, are not dealt with in much detail and the expected showdown between Karloff and the callous warden (James Stephenson, who would die only 2 years later and whose best role was his Oscar-nominated turn in William Wyler's THE LETTER [1940]) never occurs. Instead, we're made to believe that the warden's wife is so grateful for ex-brain surgeon Karloff's having saved their daughter's life that she is perfectly willing to see her husband's ruined by reporting his mistreatment of the prisoners to higher authority - when, prior to the girl's accident, she didn't seem to bother much with them since she used to frequently ride up to the labor camp, in her finest attire, as if going on a Sunday picnic! A brave and well-made B-movie all around but, ultimately, it doesn't really tread new ground and certainly doesn't carry the sheer emotional power of I AM A FUGITIVE FROM A CHAIN GANG (1932).
