This might be the most personal look at the life of the Jolie-Pitt family that fans have ever seen.

In a featurette forBy the Sea, Angelina Jolie and Brad Pitt "let loose" on set while filming in the Mediterranean isle of Gozo. This was the couple's first time co-starring in a movie together since their 2005 romantic comedy, Mr. and Mrs. Smith, and their first flick since getting married in Aug. 2014. (Fury and Unbroken were both released after the wedding but were filmed before the nuptials.)

The couple looked so relaxed while shooting By the Sea that it is sometimes hard to tell which scenes in the featurette are from the film and which are outtakes of the couple messing around on set.

At one point, Jolie entices her daughter, Shiloh Jolie-Pitt, to scare a sleeping Pitt with her slingshot. The prank goes off perfectly, and Shiloh's dad is clearly shaken up.

The A-list couple also conduct a joint interview together while sitting on the set bed, and explain the premise of the film that Jolie both wrote and directed. "When I was writing [the script], I never assumed we'd actually do it, so I wrote with a certain kind of freedom," she said.

Pitt agreed, adding, "We can experiment and play, and it's oddly a safer environment than any set I've been on before. So, we let loose!"

In another moment during the interview, Jolie seems to be hinting at her own marriage. "Everybody knows that there's never just the tragedy of life or the humor of life or pure joy of life," the 40-year-old Oscar winner said. "Relationships have those extremes. You can be absolutely madly love the person you want to kill."

Gushing over her 51-year-old husband, Jolie continued, "I was so happy that he was willing to try this."

Pitt said his role in the film was "one of the most challenging things" he's ever taken on as an actor. 

Set in France during the mid-1970s, By the Sea follows former dancer Vanessa (Jolie) and her husband Roland (Pitt), an American writer, as they travel the countryside together. The couple seem to be growing apart, but when they linger in a quiet seaside town, they begin to draw close to some of its more vibrant inhabitants.

"Brad and I have our issues," Jolie said in the November issue of Vogue magazine. "But if the characters [in By the Sea] were even remotely close to our problems, we couldn't have made the film."
