The Princess of Alderaan would have been such a better title…
I’ve seen that passed around, & I disagree.
If Leia was the main character, maybe. But it’s clearly Luke’s story.
(Also, the aping of Edgar Rice Burroughs is right on the nose. Dunno If I hate that or love it.)
Leia may not be the main character, but she sets things in motion, and keep them in motion. She’s basically giving (direct and indirect) orders to the male characters throughout the movie!
For a less Burroughsian title, I suggest The Rebel Princess. I think it goes well with the other titles in the trilogy, said trilogy being about the Jedi, the Empire, the Rebels, and a Princess…
