Is the element of suspense universal?  Or is it generational?  Is it about what is overtly portrayed on the screen by a good director, or what is merely insinuated?  Is it about action?  Horror?  Does it entail surround sound, at high volume, or subtleness?  A good soundtrack paired with good editing?  

I'm not really referring to cinema's most scariest moments...but rater its most suspenseful moments.  Most ominous moments.  Most cinematically creative moments that pulled you to the edge of your seat, made your breathing a bit shallow, made you nervous, that sucked you in and hooked you.

Those moments can come at various points in any good film.  Sometimes it is the opening sequence.  Other times it is mid-film and, obviously, it can come at the climax.

What are the film scenes that made your stomach immediately tense up, and remain with you long after seeing the film?  I'll share some of mine below the squiggle.
