4. Arnold Schwarzenegger

Once Mr. Universe, the world’s highest-paid action star, and one of America’s most powerful politicians, Schwarzenegger is not just a shadow of his former self.

The Austrian actor-bodybuilder’s career got really shaky once he confirmed that he has a 14-year-old kid with his then-housekeeper, Mildred Baena.

To add insult to injury, at this time Schwarzenegger got divorced after a 25-year marriage with Maria Shriver.

As for his acting career, Arnold has been keeping a low profile ever since the divorce fiasco, up until his role in “The Expendables,” where he played next to some all-star action heroes like Silvester Stallone, Bruce Willis, and Jason Statham.

Regardless of his efforts, Schwazenegger can’t seem to achieve the same popularity and fame as he had when he played in “Conan, The Barbarian” or “The Terminator.”
