Derailing the thread a little, the music is what gets me on several occasions. Binary Sunset aside, one of the scenes that gives me huge goose bumps is the part where Luke attacks Vader in ROTJ and the music swells to dramatic portions. You see Luke's saber strike harder and faster and the music is Luke's theme but all dark and somber and you see son against father in a final emotional battle ... wow. I've got chills on my arms just thinking about it.

And it's not in the movie, but a longer extended version of the Funeral Pyer music brings me to tears every single time I hear it.
