And that’s just what they did. But it hasn’t always easy, especially when Samuel became addicted to drugs and was unable to be there emotionally for his family. It was LaTanya who helped him get into rehab in the early ’90s. Samuel has now been in recovery for more than 30 years and credits his wife for helping change his life for the better.

Today, his films—including massive franchises likeStar Wars,AvengersandThe Incredibles—have collectively raked in nearly $18.5 billion worldwide, making him the highest-grossing actor of all time.

But Samuel is modest about being called a Box Office King. “Coming from the kind of backgrounds we come from and the people that raised us, we learn that we’re not better than anybody else,” he says. “A job is a job. We were fortunate enough to have a job.”

LaTanya—whose career has also thrived, including her 2014 Tony nomination forA Raisin in the Sun—jokes that her husband is “an anomaly” because he “loves every job he does.Snakes on a Plane, I’m like, ‘Really?”

Every July, the actors stops working to spend quality time as a family. They often take Zoe and friends out on a boat, where Jackson says there is only one rule: “Don’t wake anybody up. You sleep when you sleep. Then we come together and eat.”
