Matt Damon spent most of the True Grit shoot in the air - he regularly flew home to New York from the film's set in Texas to see his family.
The actor hates being separated from his wife, Luciana Barroso, and their children and insists on a "two-week rule" when he takes on any movie jobs - telling his bosses he cannot go more than 14 days without seeing his loved ones.
And True Grit directors Joel and Ethan Coen happily accommodated Damon's home life by fixing his schedule so he could jet to the Big Apple at least once a week.
The actor tells CNN's Piers Morgan, "We don't do well when we're apart and I don't wanna be apart from my kids.
"For instance (with) True Grit, my deal with Joel and Ethan was I told them about the two-week rule and they scheduled the movie so that I was actually never away from the family for more than one week.
"I was like a travelling salesman - I'd get up, go over to Newark (New Jersey airport), catch the flight, go to Texas, work for two days and turn around."
