The 39-year-old star who has an impressive catalogue of Hollywood hits has started his own production company Leverage recently. The star revealed his main reason for doing so was to build a business for him and his family.

The actor is married to model Rhea Durham and the couple have four children together including Ella Rae (7), Michael (4), Brendan Joseph (2) and 10month-old Grace Margaret. They couple are expecting their fifth child next year.

In a tell all interview in the December issue of Men's Health magazine, the Boston born actor said "A career is nice, but I want to build a business . It's one thing to have a career, waking up everyday thinking, 'OK, what's the next job?' But I want to build something that can last forever, something that my kids could venture into if they were interested.

“I'm in a unique position of doing things that I can be very proud of and excited about. I might as well take advantage of that now because it definitely might not exist later."

The screen star admitted that his approaching 40th birthday is on his mind: "I think about 40 every once in a while. Especially as I am working like a psychopath right now . But my life has evolved so drastically over the years in every aspect. I embrace it."
