Hey, why not. What moments are the most iconic, most memorable in Star Wars movies or books?
One scene is the destruction of the Death Star. Also the duel between Anakin and Obi-wan is also a memorable scene.
"Luke, I am your father" -I doubt anything tops that moment.
In addition to the moments already mentioned, I think Vader overthrowing Palpatine could be considered an iconic moment.
From the books, the death of Chewbacca and Han Solo's reaction certainly count.
I don't think anything can top the "No, I am your father" as being iconic. Except for maybe Darth Vader himself.
I would think the lightsaber and the Force could be counted as iconic.
how about yoda's duel with sidious in rots? that was memorable.

I can't think of any moment in a Star Wars movie that tops the "No, I am your father" as being iconic.
