Natural Born Killers- The opening scene is when they kill everyone in the diner except for the one guy they let go to tell people what happened. They are killing everyone and they are so happy about it, hugging and kissing and laughing. They let you know right from the start that it was going to be a disturbing movie.
Bonfire of the Vanities. I don't think I ever saw the whole movie, but the opening scene was shot in one long take and it starts from a Gargoyle on top of a building and moves down into a parking garage and well, I don't remember the rest, but I remember it being cool and thinking, 'damn, that's really really cool.'
I Liked XXX’s opeing it was cool.
But I think the open to a Film that I remember best is the openings to the Terminator movies especially T2. Arnold walking into that bicker bar naked was so cool. He asked that guy for his close “I need your close your boots and your Motorcycle” and everyone just laughs then he kikes there Ass’s and takes the close and they play Bad to the bone…that was soo cool

The original X-Men when they are in the concentration camp and the boy is seperated from his parents and when he reaches for the fence, it starts to bend and your like- Damn- It's Magneto! I guess you would have to be into X-Men to appreciate that one.
Also, I think it was the movie "The Burbs", which was an awful movie but the opening sequence is a view of the earth from space and it just keeps zooming in getting close and closer until finally focuses on a specific house-that was a good opening. Rest of the movie sucked though.
That's all that come to mind right now but I know there is way better than those out there.
Saving Private Ryan has to be the most intense opening scene ever though.
