Star Wars - Episode V: The Empire Strikes Back

Film Moment 1
	I Am Your Father Darth Vader to Luke Skywalker: "I am your father". Wow, what a surprise (assuming, you saw the original triology first). Don't know if it has the same impact now: Episode 3 (The Revenge of the Sith) somewhat spoils the whole tragedy. That revelation was such a big twist. Amazing! And the light sabre fight before that - great stuff!
Film Moment 2
	Yoda, Luke And The X-Wing Luke Skywalker (Mark Hamill) fails to free the X-Wing out of the bog, claiming that "it is too big". Yoda giving him the immortal speech of "Size matters not. Look at me. Judge me by my size, do you? Hmm? Hmm. And well you should not." After that, Luke goes for another attempt "All right, I'll give it a try." - to which Yoda wisely replies "No. Try not. Do... or do not. There is no try." How can you argue against the wisdom of a 780 year old Jedi master?
Film Moment 3
	I Love You... Han Solo is about to be freezed in carbonit and Leia finally admits her feelings to him: "I love you" and he replies with a "I know" (looking at her worryingly). I really like this scene because what could have been a cheesy moment (if he had said "I love you, too") turned into this tragic and sad good-bye... Okay, I'm a romantic at heart!
