'Hercules': How Dwayne Johnson Got In Demi-God Shape

Dwayne Johnson invades theaters this summer as the son of Zeus in “Hercules.” How hard did Dwayne work to make this the “definite version” of the mythical hero?

I hired a great strength conditioning coach. Great diet coach. Look you get one shot to make Hercules. There's others in the past. Different actor different men over the decades. Wanted to make the definitive version. If I did that, I put a bunch of hard work in there. I am Hercules. Reporter: Dwayne had the Hercules muscle mastered but coming to the manly facial harry had to enlist the help of 4 legged friend. This is my beard and generally in Hollywood not to get any secret away but done with if lace and best Italian beard wig maker in the world. Oscar nominated and we use yack hair put open piece by piece for 2 and a half hours every day. Reporter: Getting the film made passion project for Dwayne and long time coming. First got to Hollywood in 2000. First property that I talked about. Talk to studio about. And 10 years ago slowly started to develop it so it has been a 10 year process. 10 years financially here. Make the movie and talking to you on access, life is good. Reporter: He couldn't be happier with the finished product. The movie is great. Very excited about it. Met my expectation and beyond. You never know with a biggie that big size scope. We didn't relay on green screen or crazy visual effects. So there's a great substance to it. Thousands of men and we have the big epic battle and real men and girls will like it too.
