1. Arnold Schwarzenegger
Of course it is. Did we have any doubt? The deadliest movie actor with 369 on-screen kills goes to the undisputed king of action movies. When you remember classics like Commando (74 kills in the final scene alone), Raw Deal and Predator, you can see how Arnold has blown the most people off this mortal coil. Bonus points are awarded for those original witty one-liners he fires off when despatching some poor bastard by bullet, bomb, blade or just bare hand. We might even forgive him for when things went downhill and he ended up getting impregnated by Danny DeVito.
