oh god, too many to list. but i'll try...

one movie at a time:

SW-

-the entire first 10 minutes on tantive IV. the overture, seeing the 2 ships pass overhead. R2 and 3PO being the only characters that the audience is intorduced to. seeing vader for the first time. the music once the star destroyer leaves tatooine (thank god lucas didn't rescore the imperial march into ANH)

-see r2 and 3p0 arguing on tatooine and 3P0 kicks him (more on this later)

-binary sunset

-obi-wan showing luke the lightsaber and telling him the story of the jedi

-"Listen to them r2, they're dying! curse my metal body I wasnt fast enough, its all my fault...my poor master.."

-"will somebody get this big walking carpet out of my way!?"

-luke and leia having the shootout with the stormtroopers over the chasm (a great theatre moment)

-obi-wans sacrifice

-the "POV" shot of the x-wing diving down into the death star trench. just awesome even 35 years later

-Han coming to the rescue

-throne room music and clean and shiny r2
