I have never seen Memento, but it's safe to say based on these quizzes that it's one of Quizmaster's favorites. It's the only one on this list that I haven't seen besides Ben-Hur, but I still got it because of the dozens of times it has shown up in other quizzes.
Fun fact: the animatronic Jaws shark malfunctioned (turned out it couldn't handle salt water). That's why you barely see it in the film :P Which of course turned out to be scarier!
Get them all, but had to crack my head over some of the titles, hate the brazilian distributors tendency to create movie titles instead of just translate the originals...
