13. Alien - "8th Passenger 'Nostromo'" (Poland)
Well, this particular title translation is a bit of a broken sentence (and we're sure it should read slightly better to Polish eyes) but, that said, it conveys the point: there's an eighth passenger on board the spaceship Nostromo in the Ridley Scott classic, and it's definitely not human! We think the poster for this takes the cake, though. It implies the presence of the imposter within and â€” better â€” does so using artwork that's not only anatomically questionable but which bears no aesthetic relation to what the movie is all about. Win.
