Oh this is an old thread but I have a couple of favorite ones.
My first favorite since forever is the opening scene of "Sound of Music" where Maria is up on top of the mountains, running, twirling, singing. I just could watch it a million times and live there.
But in recent years - you guys don't know this
.... I started getting into Westerns. The one that got me good was "The Good The Bad and the Ugly". There are so many good scenes. But my favorite one is when my favorite character Tuco, goes into the graveyard and starts running, looking for the grave. The music and the spinning of the camera and fast searching of the gravestones - it's amazing and I've never seen anything done like that. It's just a whirlwind and grasps me every time.
