UPDATE:
The barrel actually kills two people, Chico (Mario Brega) and some extra.

I loved that death scene. But of course
they rig the barrel to blow up
so as to make it more visually dynamic. Instead of rolling over the guy, the barrel literally explodes.

Yes amazing scene!!!
When you have to shoot, shoot, don't talk

That was laughable. It was an
EMPTY BARREL
. If the barrel had actually had something in it, sure, that would have been an awesome kill. But empty barrels don't kill people.
I want the doctor to take your picture so I can look at you from inside as well.

It's pretty great. But what about the barb-wire fence in Final Destination 2? I found that one pretty amusing. I never would have thought a fence - AN ENTIRE FENCE - could pull off such an acrobatic feat. That has been my favorite kill scene ever since I saw it. (And ridiculously enough, I'm afraid it DOES count as a "kill" and not just a death.)

It's a good scene, but if you are going to use the word "cinematic" you are way off. Cinematic would be better to describe the kill scene in Swordfish when the bomber vest goes off on that girl getting pulled away from the bank and all the bearings going through every one.
Since I like to laugh, I would say the best kill scene in the movie is when Eastwood asks the Baxter's men to apologize to his mule.

fact, the buddy and I rewound that scene like 50 times when we were 8. lol.
Can't keep me off this escalator!

HAHA I still laugh whenever I see that scene. MAN CHICO ATE IT!!!!!
But my favorite is the "get hit w/ toxic waste then liquified after getting by a car" death as seen in RoboCop 1.
