Matt Damon isn’t the spanking kind of man, even though he plays one in the movies.
In a key scene in the new Coen Brothers Western True Grit, Damon, playing a boastful Texas Ranger, takes his costar Hailee Steinfeld – who turned 14 last week – over his knee and wallops her with a wooden reed. But that’s a long way from Damon’s real life with his four young daughters.
“I definitely don’t spank ‘em,” the star, 40, told PEOPLE at the movie’s New York premiere on Tuesday.
