10 Most Evil TV And Movie Politicians

10. Greg Stillson - The Dead Zone

After a very Stephen King-esque car accident, teacher Johnny Smith (Christopher... Walken) takes a knock to the head and wakes from the subsequent coma with the ability to see into the future. Initially using his gift to save a young girl from a fiery grave and to stop a violent killer, Johnny finds his true calling when he meets Senatorial Candidate Greg Stillson (Martin Sheen).

Shaking Stillson's hand, Johnny has a vision of the charming politician eventually becoming President of the United States and ordering a nuclear strike against Russia.

Cue nuclear winter and the end of the world as we know it, presumably. While Johnny's attempts to assassinate Stillson are ultimately futile, he does manage to damage the politician's reputation enough to prevent nuclear armageddon.
