Some movies seem to be made solely on the strength of one very good scene (making the rest of the movie filler). Nevertheless, my favorite scene has to be the "stunt double" from "I'm gonna git you sucka." maybe its because the whole movie was kind of meh, making that scene all the more surprising and funnier.

post yours

I like the scene in Punch-Drunk Love after the brothers ram into Barry's car and he sees Lena is bleeding he gets out of the cars and kicks ass.

I don't have just one favorite (so I might post again) but this one comes to mind.

The whole tansformation sequence from Murphy to Robocop, from the execution sequence to the part where he first sees himself in the TV monitors as he walks past the crowd of exec-techs. I shed tears in the middle part.

Probably the scene in Werckmeister Harmóniák where János explains the movement of the planets to the bar full of drunks.

For a combination of cinematography, music, plot revelation and star power, this is pure movie magic.

The "Don't Stop Me Now" setpiece in Shaun of the Dead.

That's a great one, but you can't forget when he trashes the bathroom.
Oh, and Stand By Me's "pie-eating contest" scene is one of my favorites.

Yes! "Sir, I'm gonna split you're fucking head open."

Kill Bill Vol. 2 - When the bride is buried alive. Outstanding use of the surround channels.

Excalibur - "Come father, let us embrace at last"

The "100-Mile Dash" in The Incredibles. An action sequence that's just as much about character development as it is thrilling cinema? I'm in love!

Heat - DeNiro/Pacino coffee scene

http://www.youtube.com/watch?v=cYSzx_zy-98

The moment in IT'S A MAD, MAD, MAD, MAD WORLD when the entire star cast suddenly realizes that Captain Culpepper (Spencer Tracy) is not heading back to the police station with the case of money but is heading off on his own and they scramble back into the two cabs to give chase. I leap up in my seat every time I see that.

There are two scenes That come to mind.


Children Of Men - walking out of the building with the baby


28 Days Later - Walking out of the Hospital

gotta add the "why so serious" scene from the dark knight

JAWS

Quint's U.S.S. Indianapolis speech

I also like the part where:

little Alex Kitner loses a couple legs on a raft. Just a nice wholesome moment for the whole family to enjoy.

Die Hard where John jumps off the building with the water hose. You know your situation is fubar, when that was the best thing to do.
