While I've never considered it as good as some of the true classics in Arnold's extensive filmography - Total Recall being far and away the best of his cinematic exploits, as far as I'm concerned - I must admit to having devoted several hours of my childhood watching Predator on more than one occasion. Thanks to British grime/rap group The Anomalies, who put the video together over a period of nine months, I can now see all of the highlights from the movie in just six minutes. (link via Grindin')
For those looking for a little more Schwarzenegger with their music videos, the late, great Disco D remixed a documentary on Carnivale that Arnold appeared in a couple of years ago. Links to that over here.
