“Nazi Overlord” (** out of four) was a wholly derivative but entertaining horror thriller in which a D-Day invasion becomes ugly when a determined group of American soldiers (Anthony Jensen, Matthew Amerman, Greg Furman) become trapped behind enemy lines and find that the Nazis are performing numerous experiments on soldiers and they struggle to escape. The kind of B-movie that is bankrolled to capitalize on the success of a much larger-scale one (in this case “Overlord” if you hadn’t guessed) but the story, title, and even characters are so copied it’s almost plagiarism. Having said that, it’s fast-paced and features plenty of action and cheeky humor. Dominique Swain shows up and adds some style as a Nazi doctor and Tom Sizemore as a cameo as the boy’s sergeant.
