How about the end of the movie when the Death Star goes boom?
The opening Star Destroyer shot.
The first appearance of the lightsaber.
The Falcon first goes to light speed.
Leia shooting a wall and snapping that "Somebody has to save our skins!".
Luke and Leia swinging across a bottomless pit.
During the Death Star battle, Luke has an enemy on his tail. Does Wedge come up behind the bad guy and blow him up? No. He comes at them head on and weaves between Luke and the TIE fighter to take his shot.
The Death Star trench dive shot, done twice, and awesome both times.
Luke taking charge during the final Trench Run. Consider that his wingmates are Biggs (his best friend and a much more experienced pilot), and Wedge (described in the EU as being so Badass that Imperial pilots are known to wet their beds during nightmares of being chased by him) and the inexperienced farm-boy with no more experience than varmint-hunting manages to tell them what to do.
