Best Opening Scene of a Movie

The opening scene blew everyone's minds in the theater! Nobody had ever seen anything like it before.

Their lead up to release campaign was also great. Just "what is the matrix?" in a bunch of places. Way better than trailers that make watching the movie unnecessary because they include the best jokes and action scenes. Especially since with the Matrix, the whole premise of the plot was the twist, so they couldn't really give you anything.
