Dwayne "The Rock" Johnson takes on the legend of Hercules in this epic movie.

How serious did the 41-year-old actor take this endeavor? Aside from getting up every morning, for 8 months, at 3:00 am to train, he put so much energy into the pivotal scene where he yells, "I am Hercules!" that he actually passed out every time he did it.

At 6 feet 5 inches, the ridiculously ripped Johnson said he trained harder for Hercules than any other role. Now that's dedication.
