If the original Star Wars trilogy were made in the 21st century, the trailer would most likely look like this, a typical modern trailer modeled after the preview for Avengers: Age of Ultron. The clips are good, and would certainly make me want to see the movie. However, it doesn’t tell you anything about the plot. All we know from this is that the young fellow is the good guy, and the guy with the black mask is the bad guy, and they fight. There’s no indication of which side the other characters are on. Contrast that with the original 1977 Star Wars trailer, in which the narrator makes those alliances very clear, yet still makes you want to see the movie.
The one constant in blockbuster movie trailers is that both will show off the state-of-the-art special effects. I doubt that will ever change. -via Tastefully Offensive
