The Footloose one that was floating around in the mid-2000's.
It ended up getting taken down for some stupid reason.
It was spelt in 1337speak IIRC;
Like F007l00s3 or something.

Edit: I remember it very specifically opening to a clip from Advent Children over dubed with audio form the Footloose film, as to differentiate from the others that have been recently posted.
