As for the video series, it features many off-camera moments of Roberts “spreading her joy and larks. She knits, finds something nice to say about everyone, slips into trainers under her glamorous dresses, takes over the camera herself and interrupts her script rehearsal to cuddle her dog Myrtle that jumps on her lap,” the release said.

“Julia Roberts is that rare thing: a genuine movie star,” Gray said. “She also happens to be a person with a tremendous sense of humor about it all, and somehow, she hasn’t let her legendary status go to her head.”

The director continued: “I always jump at any chance I might get to work with her. Both Julia and Chopard embody a true sense of happiness, so it was a wonderful opportunity to work with them on this campaign.”

Roberts also shares her best fashion memory, wearing Chopard at the 2016 Cannes film festival.

“The first time I was there, running late and racing down the hallway,” she recalls. “Somebody was still sewing me into my dress, so we were all running down the hallway to the elevator and somebody was sewing away. And I just thought ‘It’s so classic’. It was a “Cannes”-Do moment.”

Two years ago, the actress was named thenew face of the legendary Chopard collection, telling PEOPLE exclusively at the time that the best part of shooting the corresponding campaign and short film with director Xavier Dolan and photographer Shayne Laverdiere was “how much fun we had doing it.”

For Roberts, whose infectious spirit has been lighting up Hollywood since the early ’90s, “Pure happiness is the feeling one has when the people they love are happy.”
