What was the best scene from an Action/Thriller you ever saw?

The chase scene from Bullitt or The 7-Ups

The final twist ending/reveal at the end of the original Saw. Chilling ending

Final Encounter with John and Hans and Hans Gruber falls from the top of the building. "Happy trails, Hans" from the Die Hard.

The bathroom fight from the Bourne Ultimatum. Best fight scene in the history of action movies.
