It’s been 20 years since Brad Pitt and Angelina Jolie took a lot of shots at each other and blew all sorts of things up in Mr. & Mrs. Smith.

You’re forgiven if you mainly think of Mr. & Mrs. Smith as the movie that brought Angelina Jolie and Brad Pitt together.

The Doug Liman-directed action thriller about married assassins who don’t know what the other does for a living until they’re tasked with killing each other is an entertaining romp. And the premise had enough juice to inspire the recent Amazon series of the same name starring Donald Glover and Maya Erskine.

But by the time the film hit theaters on June 10, 2005, Pitt and Jennifer Aniston were in the process of divorcing and, a month later, he was with Jolie in Ethiopia when she adopted daughter Zahara.

And all that, needless to say, kinda dominated the headlines.

Which, incidentally, didn’t hurt the movie—Mr. & Mrs. Smith made almost half a billion dollars worldwide— and everyone who chose sides (there were T-shirts and everything) 20 years ago knows now that marriages and why they end is a complicated matter.

“I think we were both the last two people who were looking for a relationship. I certainly wasn’t,” the then-twice-divorced Jolie reflected in the January 2007 issue of Vogue. “I was quite content to be a single mom with [son Maddox, whom she adopted in 2002]. And I didn’t know much about exactly where Brad was in his personal life. But it was clear he was with his best friend, someone he loves and respects. And so we were both living, I suppose, very full lives.”

At the same time, Jolie has come right out and shared that the Mr. & Mrs. Smith set was where their feelings developed.

“Not a lot of people get to see a movie where their parents fell in love,” Jolie told the New York Times in 2008, saying she was looking forward to screening the film for the six children she and Pitt shared by then.

Of course, family movie night has a different tenor now. The longtime couple eventually tied the knot—their kids really wanted them to, Jolie said—in 2014, but she filed for divorce two years later. She and Pitt were declared officially single in 2019 and they just settled their divorce in December.

“I don’t think it was that major of a thing,” Pitt told GQ recently of the latest development in their messy split saga. “Just something coming to fruition. Legally.”

And to think, Jolie wasn’t even supposed to be in Mr. & Mrs. Smith originally. But she was, and this is what happened—and more behind the scenes secrets:
