Return of the Jedi

I remember the last scene in Star Wars Movie Trilogy, when Luke Skywalker open the mask of Darth Vader (his father), and saw real face of Darth Vader, and the rebel destroy death star.

I like this part of film very much, I think George Lucas is best Sci-Fi movie director and writer, especially when change  episode (1,2,3) to episode (4,5,6) and present new parts (1,2,3), where the parts told story before old episode (4,5,6), these parts told story of Darth Vader and how changed from Jedi side to Dark Side.

George Lucas liked to use power of Visual Effects, digital sound and vision, I remember the sound of TIE fighter when fly near death star, and X-Wing fighter when fire Lazer weapons, do you remember these sounds?

in final who don't remember the themes and sound track of star wars, its from John Williams, the best composer and conductor of Sci-Fi movies, like: Jaws, Superman, E.T. the Extra-Terrestrial, Raiders of the Lost Ark, Jurassic Park, Schindler's List, Hook, Harry Potter and Star Wars, what's your favorite Sci-Fi film?
