Will Ferrell and I are teaming up again on a film called Daddy's Home. In the movie I play a Special-Ops soldier who has just discovered that Will Ferrell's character is married to my ex-wife and is my children's stepfather. So, I have to come home and try to win them back and take him out.

He's a legend and I respect his work, so I went down and paid my respects when Charlton was on the set. He was nice but I think he lied a little. He said it was an honour to be in a movie with me, but I don't believe it.

That whole world, the world of bodybuilding to me is fascinating. It's such a unique and interesting culture, and everything about it appeals to me.

I'm fortunate that my job gives me the motivation to be as fit as possible. I wound up in a profession that requires physical and mental preparation, so I get to prepare like an athlete for everything I do. I'm living the dream, man.

If I'm not training then, gosh, anything: donuts... Kentucky Fried Chicken 20-piece hot wings... corned beef hash and eggs... But because I'm training, I'm eating very healthily: almond milk... Ezekiel bread... chicken... fish... I'm on a strict diet.

The best part of a great movie is a great villain and I usually have a tendency to root for the bad guy.

I don't go to Mass every day. But I go to church every day. Just sitting there, thinking - it's a great way to start the morning, you know? You feel so good coming out, and your approach to everything is suddenly really clear.
