What’s your favorite line/scene?

Mine is Vader finally getting rid of Ozzel. Guy repeatedly defies the dark lord like nothing will happen to him. Then gets used as an example. Piett learned really quick.

The Battle of Hoth is probably my favorite part of the movie, although the Vader plot twist (you know what I'm talking about) is a close second.

Pretty much any interaction between Han and Leia. Their chemistry in ESB is nothing less than perfection.

Leia: ”I’d just as soon kiss a Wookiee”

Han: “I can arrange that

H: “No time to discuss this in a committee.”

L: “I am not a committee!”

Cloud City, Lando comes in, flirts with Leia, invites for refreshments. Then he sees the dismembered C-3PO.

Lando : "Having trouble with your droid?"

Han : "No. No problem. Why?"

Han Solo walks into a banquet, sees Vader sitting at the table, and just pulls his blaster out and starts shooting.

Everyone else too stunned to do anything, and Han doesn't even need to think. Shoot the bad guy now, worry about the rest later.

Really tough, since this is my favorite one overall.

I'd go with "Do or do not. There is no try."

Anything from Dagobah. From the introduction of Yoda, to the lifting of the Xwing is the best.

“Luminous beings are we…not this crude matter.”
-Yoda

The description Yoda gives of the force in that scene jives with so many larger (current) metaphysical questions - that is the point where the whole Star Wars story/mythos takes on a larger role - that later becomes such a large part of culture that we're here playing with it 40+ years later.
