Enter the Ninja

Enter the Ninja is a campy movie about an American ex-soldier who trains to become a ninja in Japan, and then goes on to help his American war buddy fend off the henchmen of a nefarious American real estate tycoon who wants his buddy's plantation in the Philippines. The film is an awesome example of a cheesy martial arts movie from the 80's directed by Menahem Golan himself (of Golan-Globus and The Cannon Group fame). transient-2 sums up the flick nicely on IMDb with a comment hilariously titled, "ninjas take the elevator..."
