when Steven Seagal got sucked out the airlock in Executive Decision, i was extremely happily surprised!

and in Children of Men, that car interior scene. Wow. Just a beautiful blend of technical, storytelling, acting, cgi, everything in one.

I guess given the title of this thread it's assumed all posts would be "spoiler" posts.

oh and 6th Sense, that suprised me at the end.

and Braveheart, for cold blooded, when he cuts the magistrate's neck for killing murren. wow. that was cold blooded and a half.
