Xtro 3 takes place on a deserted island where a group of Marines try to figure out just what happen at their Japanese intern camp. Once they land, they find an alien spacecraft and an ET looking creature living inside it; thereupon, all hell breaks loose. I actually enjoyed this sequel more than Xtro 2. The film has an enjoyable plot and alien effects; nonetheless, it can become too rakish for some people. Look closely for Tom Hanks's brother Jim Hanks, who has a supporting role.
