The 40-year-old actor - who raises 12-year-old stepdaughter Alexia and daughters Isabella, four, Gia, two, and four-month-old Stella with spouse Luciana - believes it is possible to strike the right balance between personal and professional commitments.
He said: "I try to have my cake and eat it. On the one hand, I`m most excited and alive when I`m working on something I love. But not to the detriment of my family.
"Clint Eastwood will shoot a 10-hour day, which is the regular hours parents go to work. It`s a great creative experience and then I`m home with my kids."
Matt - who has been directed by Clint in `Hereafter` and `Invictus` - also revealed he takes longer to prepare for movie roles these days because he hates having to diet beforehand.
He explained to Britain`s Glamour magazine: "I exercise better than I used to. I have trouble cutting out all the food I like, so I start getting ready for movies by preparing earlier.
"I could eat a 10-course meal every night if you let me."
