Most tense scenes

[my_name_is_neo]

What scenes in a movie created the most tension in your opinion?

IMO:

Joy Ride - the climax

The Fog - the whole movie

Halloween - Michael Myers stalking Laurie Strode

Phone Booth - almost the whole movie

Jaws - the opening (the rest of the movie, while I kind of liked it, didn't even approach this scene in tension level, IMO)

[syxxpac]

The Mexican standoff in Reservoir Dogs comes to mind.

[therealjohng]

The final 40-45 minutes of Aliens.
Adrenaline shot to the heart - Pulp Fiction
Mexican standoff - Reservoir Dogs

[EvilDeadGirl]

I'd have to agree with Syxxpac and therealjohng that the Mexican stand off in Reservior Dogs. Now that's a tense situation if I've ever seen one!

[Jerk Shapiro]

The last few moments of Se7en had me shaking, literally.

[Raoul Duke]

Most of Punch-Drunk Love.

The climax of Panic Room

Adrenaline scene in Pulp Fiction.
