3. Chev Chelios
The two Crank films to date have reveled in the ridiculous, and specifically, the notion that Chev Chelios (Jason Statham) continues to live in spite of everything we know of human physiology. He is hurled from the top of a helicopter at the end of the first film, appears to "die", before having his heart replaced with an artificial one at the start of the second film, which requires constant electrical charges. He ends that film with his heart replaced once again; yes, this is a man who has survived, above all else,
two heart transplants. Is there really much more than that to say? The guy should obviously be dead, and it's awesome that he isn't. As the sequel's poster says, he was dead...but he got better.
