The Marine Corps is the Navy's police force and as long as I am President that is what it will remain. They have a propaganda machine that is almost equal to Stalin's.

Oh and once when I was in the Marines I got a perfect score on my physical fitness test.

Nothing drew me to the film business. I was propelled by the fear and anxiety of Vietnam. I had been drafted into the Marines. My brother was already serving in Vietnam. I bought if you will a stay of execution - both literally and figuratively - and went on to graduate school of business from the law school that I was attending.

So the Marine Corps really did teach me to conquer fear and then to go for higher causes higher purposes.

My Marine experience helped shape who I am now personally and professionally and I am grateful for that on an almost daily basis.

My dad was a golden gloves boxer in the Marine Corps then a deputy sheriff. My mom worked as an office assistant.

My dad was a Marine. He was one of the Montford Point Marines. Those are the equivalent of the Tuskegee Airmen for Marines. He's a tough tough guy. When I was 15 we had a fight and I didn't speak to him for 10 years.

Our film examines the heroism courage and prowess of the Soviet submarine force in ways never seen before.

I've done four other films since 'Submarine ' so that's quite cool. It's just good to have people respect your work I've never had that before. Yeah my life has changed crazy. I'm a kid from a small town in south Wales I play my Xbox usually and all that sort of stuff and it's a whole new world.

I get letters from kids teenagers and young girls who just want to be Mac. I've had quite a few people actually say that they're going to become a Marine or a JAG lawyer because of me... the character. I think that's pretty cool!
