Kill Bill part two David Carradine makes a sandwich with a surprisingly large chef's knife and condiments of dramatic tension and physical grace.
The Royal Tenenbaums Gene Hackman physically and emotionally reaches out to his children for the first time after a lifetime of neglect. His son Ben Stiller double-slaps the hand away as if he were offering a Frenchman to duel.
Jaws Richard Dreyfuss is tying a line of barrels together. If he can't do it in time, he will be eaten by a shark. If he takes too long, his hand will be caught and mangled in the rope, and then he will be eaten by a shark. He does it in the nick of time. (There may have been some movie magic involved in this one; Richard Dreyfuss's life was probably not in danger.)
Honorable Runners-up: Josh Brolin takes a bunch of screen time in No Country For Old Men to build some kind of doohickey that can push a big bag of money into a ventilation shaft.

Brandon Lee blows off a direct order from police in The Crow by doing a silly skittering dance to stage right. "I say I'm dead...and I move."
