The Paperboy actor, who is the father of a young daughter and son with fiancée Camila Ives, said that the games he plays with his family allow him to be a better actor.
"It is more fun," McConaughey explained to People. "More things sound more fun to do, because the kids remind you to play make believe and that's what we are doing. If we do it well, we make you believe."
The Killer Joe star, who recently moved with his family to Austin, Texas, went on to say that the city is a good fit.
"Austin is more of an identity town than it is an industry town. It feels good to be back home. It feels good to have my family here, my kids here," he said.
