When I intended to create this series of posters there was one thing clear, the original trilogy posters had to be a space-like poster and the prequels a planet-like poster, why? Because it's just that!
The original trilogy is more about epic space battles, amazing asteroid chases and superstar destroyers, prequels instead are about lightsabers, planets, colors and of course the clone troopers.
So, I decided to divide the themes like that. When I started making them a year ago I wanted to make them special. The Phantom Menace was to me the most difficult one to make, because what is the phantom menace? I try to picture the essence of the whole movie, was it the shadow of Darth Vader? The rise of chancellor Palpatine ? Or the Sith? What is the best way to represent them?
I made a Darth Maul watching the horizon of Tatooine, Anakin's home planet and off course Luke's too, while the twin suns set over the horizon a shadow or a phantom menace (perhaps) rise over it as you see Vader's helmet rising. And you can finally see it full on in the Revenge of the Sith poster, with the Coruscant cityscape and the Jedi Temple on fire, that's the moment Anakin turns in to Lord Vader... that part where he kills the younglings and takes over the Republic.
The trilogy was a little less challenging to make, my favorite is perhaps the Return of the Jedi poster. With the retro colors and the way that the two lightsabers clash is one of the most iconic scenes in the movie and I wanted to represent that while also not leaving behind the amazing second Death Star.
