This is the climactic scene from the anime film Metropolis. It gets my vote for the best deployment of a Ray Charles song. It's a little hard to tell from this edit, but the video begins with a bloody finger pushing a button.
This movie is, of course, a re-imagining of Fritz Lang's 1926 film, Metropolis. For the Philistines that have never seen the original film, I'll let the rock band Rammstein give you a quick plot summary.
