An odd mishmash of a film based on a Wheatley novel (not a horror novel but written in the vein of William Hope Hodgson's weird sea tales) not entirely successful really but I had to see it in my quest to see and read everything remotely connected to the works of that crazy, jingoistic, occult obsessed weirdo Wheatley who wrote some seriously great and some seriously lame novels.
Not as successful an adaption as the earlier Hammer film version of "The Devil Rides Out".
