Robert Downey Jr.'s wife has opened up about their marriage, including one "rule" that has helped keep their romance alive.
Robert and his wife Susan Downey met when he was working on the movie Gothika which Susan (then Susan Levin) was producing through her job with Silver Pictures.
Initially, Susan was apprehensive about getting romantically involved with Robert due to his fame and the fact that they worked together.
She also told the Hollywood Reporter that she found him "interesting but weird".
However, the pair were engaged a few months later and then two years after that they tied the knot. They now share two children and have a production company together called Team Downey.
But what is the secret to keeping the romance alive, given that both are very busy, successful individuals?
In an interview with PEOPLE, Susan shared insights into their family dynamic and how they navigate their busy lives.
The Downeys adhere to a strict "two-week rule" to ensure they don't spend too much time apart.
"We do have a two-week rule, which often feels too long, but we don't go more than two weeks without seeing each other and the family being together," Susan said.
With two children, Exton, 12, and Avri, nine, together, and Downey's eldest son, Indio, 30, from a previous marriage, the family values their time together.
Susan added: "You keep the basic rule of two weeks, and then you don't try and think too far ahead, because so much of what we do is oddly unpredictable. You just never know.
"Someone might get sick, or there might be a shutdown, or this or that. So you just have to have some basic things in place, and then you have to be willing to flow with the rest of it."
Despite the challenges, Robert cherishes the stability and joy their family life brings. "It just gives me, honestly, something to attach my neurosis to that's positive," he said.
Susan acknowledged the flexibility her role as a producer affords her compared to her husband's on-screen commitments. "The good news is I'm not in front of the camera, and so as a producer I end up with a little bit more flexibility in terms of location, of where I would need to be."
Expressing admiration for couples who juggle careers in front of the camera, Susan empathized with the tough choices they often face.
For his upcoming project, Robert dives back into acting with the HBO series The Sympathizer, premiering April 14. The series sees him portraying four distinct characters, showcasing his acting talents once again.
"He approaches everything he's done, every Marvel movie, every other movie, with the same level of commitment and belief that he is an actor and that he's doing his best to create a role," Susan praised.
"But sometimes I think it looks so effortless that it's just like, 'Oh, yeah, that's just Downey being Downey,' when it's like, 'No, there's a lot of craft and skill that is going into the performance.'"
