John McClane is a tough, crude, wise-cracking, chain-smoking New York City cop whose been on the force for many years. This has greatly effected his personal life so much so that his marriage to his wife Holly is dwindling. John always seems to find himself at the wrong place at the wrong time, and being the good guy that he is he reluctantly steps in where there's trouble because no one else will. This is what makes him someone we will most always root for because of his relentless efforts to not give up and get the job done by whatever means necessary. Played by Bruce Willis in four of the Die Hard films, John McClane is one of our great heroes in cinema that everyone would want to be there in a life and death situation.
