George Clooney fits his schedule around his wife Amal's.
The Monuments Men actor and spouse Amal have a "marriage of equals" and because the human rights lawyer's work is less flexible than the Hollywood hunk's, the 54-year-old star is willing to fit his filming around her commitments.
A source said: "When he proposed, the deal was struck on very clear terms. This is a marriage of equals, and Amal takes her work far too seriously to make compromises, so the only way it can work is if George fits his schedule around her.
"It may sound harsh, but that's the reality. If your name is top of the bill, you can sort out filming schedules to suit you. Amal can hardly order an international court to adjourn to gad about Hollywood.
"George understands it, it keeps him on his toes and I've never seen a more blissfully happy couple."
Despite being one of the world's most desirable men, insiders insist Amal never pursued George, and the Oceans 11 star had to work hard to woo the 37-year-old lawyer.
The source told Grazia magazine: "In the early days, people totally misunderstood the dynamic of the relationship. They saw it in the traditional terms of beautiful, younger woman falls for successful alpha male.
"Anyone who was there at the time will tell you it was George who did all the chasing. He had to do his homework just to get Amal out for dinner and ever since then he's been running to keep up.
"She's always been totally unfazed by celebrity and that's one of the great strengths of their marriage."
